Chapter 107 Chen Jianlin: Regular results, don’t worry!

 The excitement of Peng Hui, Shi Guifang, Wan Yiming and others is justified.

They manufactured a new titanium alloy with a tensile strength that reached the world's top 1,400 MPa. At the same time, the manufacturing process was relatively simplified. It was indeed an exciting result. It can be said that the expected goals of the project research were achieved.

Titanium alloys are a field of materials that the world attaches great importance to. Many institutions are conducting relevant research, and there are also many types of titanium alloys.

Distinguished from the internal matrix structure, titanium alloys can be divided into α alloys, β alloys and (α+β) alloys.

In China, they are represented by TA, TC, and TB, each of which has several or more than a dozen models. In other words, there are as many as twenty types of standard titanium alloy materials sold on the market.

There are many types of titanium alloys, mainly related to their application directions.

In the application field of titanium alloys, it does not mean that the higher the strength, the better. In fact, if we just compare the strength, the highest strength of domestically produced special steel can exceed 2000 MPa, which can be said to be internationally leading, but that kind of steel

Without plasticity, processing and welding are big problems, and the application difficulty will be very high.

The biggest advantage of titanium alloys over special steels is that they are light because the density is relatively low. For the same volume, the weight is only about 60% of steel.

Because of its low density, titanium alloys are widely used in the aviation field. Many parts of aviation aircraft and military aircraft are made of titanium alloys.

However, the disadvantages of titanium alloy are also obvious. The biggest disadvantage is that it is expensive.

Titanium alloys are expensive not because of the low titanium content, but because the titanium element reacts very easily with many other elements at high temperatures. It will be very troublesome to get titanium out of other impurities, and in the end

When forming, it is often necessary to operate in an inert gas or vacuum environment.

Such a complicated operation means that the price of titanium alloy materials will be very expensive.

The laboratory uses refined titanium to make titanium alloys. Operations at high temperatures also need to isolate air. The process seems simple, but in fact, because it is a laboratory operation, only a small piece is made, and some need to be isolated.

The air steps are all performed in professional equipment.

The second disadvantage of titanium alloy is that it is difficult to process and weld.

There is an example that can directly illustrate that Amrican is a fighter jet called the 'Immortal Blackbird'. It can fly at a maximum speed of Mach 3 and is called the fastest aircraft in history. The reason why it can fly so fast is because

Thirty tons of titanium alloy were used, and most parts are made of titanium alloy.

However, this aircraft has a very obvious shortcoming, which is oil leakage.

Ameriken tried various methods but could not solve the problem because they had not mastered the perfect welding technology of titanium alloy at that time.

This is enough to show how difficult it is to process and weld titanium alloys.

However, at present, China has mastered high-end 3D titanium alloy printing technology, which can directly shape corresponding parts with 3D printing, skipping the welding process.

This is off topic.

The project carried out by the Metal Laboratory is the research on super-stressed titanium alloy materials. The purpose of their research is not to apply it, but to specifically study how to improve the strength of titanium alloys produced at "normal costs."

Internationally, the highest strength of titanium alloy can reach 1,700 MPa, but it is manufactured by abnormal means and cannot be widely manufactured at all.

When manufactured using conventional methods, the final compressive strength of the finished product can exceed 1,400 MPa, which is already a very high figure.

This project belongs to 'materials research' rather than 'materials application research'. The titanium alloy produced is not used to manufacture products, but to study conventional methods to manufacture titanium alloys and what processes can improve their strength.

This is of great reference value for application research on titanium alloy materials.

Other research teams working on targeted applications can improve the strength of corresponding titanium alloys based on their process references.

In other words, the manufacturing process is more important than the result.

This is why Ma Wenjun is worried about the results of other teams' research.

If the research of other teams has results, there will definitely be many experts who specialize in analyzing the manufacturing process and various data. Their alloy laboratories have done the same project, and even if it is suspended midway, the experimental data has been reported.

Comparing the two, it is very likely that problems will be found.



After the experiment was successful, Peng Hui and Shi Guifang talked a lot about Wang Hao, but he still didn't quite understand the excitement in the metal laboratory.

Because the final product produced has no innovation and no qualitative improvement in performance.

Isn’t scientific research meant to make qualitative breakthroughs? Isn’t it meant to solve unsolved problems?

After spending tens of millions of dollars and making little progress, it is really hard to find something exciting.

Wang Hao went back with some incomprehension. Perhaps there was another reason why he was not excited, because he was not involved in the project at all. He just made a small suggestion due to his good fortune.

While on the plane, Wang Hao began to count the harvest.

During this trip to Xijing Jiaotong University, I gained a lot of inspiration value. The corresponding task inspiration value increased to '79' points, which shows that I have a very good understanding of the experimental data.

This value has almost reached the peak of understanding of ‘experimental data’. Even if we study the experimental data again, it will be very difficult to improve even a few points.

When you have enough foundation, what is missing is analytical inspiration, which requires other means to obtain.

For example, research on data analysis methods, or feedback through teaching.

The latter is the easiest to achieve the goal.

Wang Hao missed his students a little. He couldn't wait to go to class, hoping to increase his inspiration value by more than 100 points.

After returning to Xihai City, he went home to rest for a day.

The next morning, Wang Hao came to school in high spirits, and when the time came, he went to class with 100% positivity.

"Probability Theory and Mathematical Statistics".

This course has entered the final stage, and when it enters the final stage, the difficulty of knowledge has also increased to the highest level, and some content involves knowledge that does not need to be mastered at the undergraduate level.

However, Wang Hao's explanation is still very detailed. He hopes that more students can understand and master it. Of course, it can also give back more inspiration value.

Teaching, feedback, mutual benefit!

After lunch, he immediately returned to the office in the complex building. After one class, he gained 20 points of inspiration.

For A-level difficulty research and development tasks, getting 20 inspiration points in one class can be said to be quite high.

This value confirms Wang Hao's previous judgment. Only with a sufficient foundation and a sufficient understanding of the experimental data can we obtain more inspiration values.

After opening the task system, he discovered something very embarrassing. The inspiration value of the task had reached 99 points.

"Only a little bit worse!"

The inspiration value is only 1 point short, and it's not just about data. He feels that he already knows an analysis method, but he is only missing the last step, but he can't get over it. It's like solving a math problem and knowing the rough solution.

I have an idea for the question, but problems arise at the beginning and I don’t know where to start to solve it.

Wang Hao could only bite the bullet and continue to analyze the data. After studying for more than an hour, there was no result. He somewhat understood why Zhang Zhiqiang often scratched his scalp.

Zhang Zhiqiang happened to look over and asked, "What's wrong, Wang Hao?"

Wang Hao sighed, "There is a question that I can't figure out."

"oh."

Zhang Zhiqiang agreed, turned around and continued to do his own thing.

Wang Hao continued to struggle with the problem.

Zhu Ping burst out laughing. She pointed at Zhang Zhiqiang and asked, "You guys are really interesting. Shouldn't you ask, do you have any questions?"

Zhang Zhiqiang immediately shook his head, "Wang Hao's unsolvable problems are all in vain for me."

Zhu Ping was stunned after hearing this, and nodded with deep sympathy. When she found Wang Hao looking at her, she immediately sat back down, turned her head and pretended to read seriously, as if to say, "Don't ask me."

,'Don't ask me'.

She even blocked her ears with her hands.

Luo Dayong got out of the state of 'thinking about life' and reminded him, "Don't do this. Don't worry, Wang Hao won't ask you."

Zhu Ping suddenly darkened her face and stared at Luo Dayong with gritted teeth.

Wang Hao burst out laughing when he saw this scene.

The daily life in the office is still very funny. I always feel that Luo Dayong is a comedian. He always gets the key point every time he opens his mouth and hits Zhu Ping's heart directly.

Hit, heart?

Wang Hao suddenly frowned while thinking, and the next moment the system prompted -

[Task 1, inspiration value +1.]

[Inspiration value: 100.]

I see!

After figuring out a problem, everything suddenly became clear. He immediately opened the computer document and started taking notes.

Suddenly a voice came from the door, "Wang Hao, are you bothering me?"

Wang Hao looked up and saw the department chair Zhou Jianchun, and said, "Director Zhou, please come in."

Zhou Jianchun entered the office and asked directly, "Wang Hao, I just met Zeng Guangxiang from the graduate school downstairs. He asked me to help ask, do you want to take care of graduate students next year?"

Wang Hao suddenly realized that the postgraduate enrollment process was about to begin, and the tutors and students must report in advance.

He asked, "How many students can I bring?"

"You really do!" Zhou Jianchun said with some surprise, "I just came here to help ask. Generally, there are two to four students for master's degree supervisors. You are in the first year. I still suggest that you tutor less students. It is best not to have any students.

I don’t need any help from students in mathematics research, so I can focus more on research.”

Zhou Jianchun was indeed a little surprised, because Wang Hao had made outstanding achievements in mathematics research and must have focused most of his energy on research. He just came to help and asked, thinking that Wang Hao would not be able to teach students.

Wang Hao is indeed very serious about his teaching work, but teaching involves giving lectures to many people and there are fixed hours. Teaching graduate students is different. You have to care about the graduate students' study progress, their papers, etc., which will definitely consume a lot of money.

A lot of energy.

Wang Hao said firmly, "I have thought about it for a long time. I must take care of students. Since there are usually two to four students, then I will take four. This needs to be reported, right?"

Zhou Jianchun nodded in confusion, and then said, "I'll just talk to the graduate school for you, and they will take care of it."

"good."

Zhou Jianchun left after asking Wang Hao. He was still very confused. After thinking carefully for a long time, he couldn't figure out what the benefits of bringing a graduate student were.

For other professors, tutoring students is the same as teaching. Students can also help with experiments, etc., which is helpful for their own research, and tutoring more students is also helpful for professional title rating.

None of this has anything to do with Wang Hao.

Because he has already achieved great results, he does not need to worry about professional title ratings. What he is doing is mathematical theoretical research, and students will definitely not be able to help him.

"Is there no benefit?" Zhou Jianchun thought carefully for a long time but couldn't think of a reason. He could only attribute it to Wang Hao who attached great importance to teaching and had a high awareness of his own teaching work.

This is also the evaluation of Wang Hao by many people in the school.



After talking to Zhou Jianchun for a few words and knowing that the graduate school would handle the problem, I put the matter behind me and continued to focus on my work.

He had already sorted out his clues and found a way to analyze the data. After memorizing the content, he immediately began to write relevant programs and use the programs to analyze the relevant data.

at the same time.

The Metal Laboratory of Xijing Jiaotong University has submitted a project results report.

Because it was a very important fund project, experts came to check it out after it was submitted, and found that they had used conventional methods to create a titanium alloy with a compressive strength of 1,400. I was immediately surprised.

"This Peng Hui is really good. He can complete the research with such a small amount of money."

"I guess the funds haven't been used up yet? I've been keeping up with the progress of this project, and there is still more than one-third left."

"Not bad, not bad, the results are outstanding. It seems that the settlement is not far away."

After briefly reading the results report, several experts felt a little surprised, because few people were optimistic about the project approval at the beginning. The funding allocated for the project by the Science Fund is limited, even if it has a certain level of research and development and limited funding.

Without support, it would be difficult to complete the research.

It was unexpected that it could be completed now, and they began to look at the submitted report seriously.

An expert was watching carefully and suddenly said in surprise, "Do you have a specially appointed data analyst on your personnel list, Wang Hao from Xihai University?"

"Is this Wang Hao the one dismissed by Donggang? The math genius who is always in the news?"

"It's true!"

"There should be no other Wang Hao at Xihai University. He is a specially appointed data analyst, and his name is very high. He is ranked fourth, even higher than a researcher from their laboratory."

"It seems that Wang Hao has made a great contribution, and Peng Hui also values ​​him very much, otherwise it would be impossible to arrange it like this..."

In the results report of major projects, a list of people who contributed to the results will be submitted. For a major project with a funding of 15 million, because there are many people involved, the list can list more than a dozen or more than 20 people.

For similar projects, we usually only look at the first few names, and the rest are just ordinary participants. It doesn't matter.

Wang Hao's name is ranked fourth, which is enough to show the importance to the results.

When several experts were studying the results report, Xijing Jiaotong University also issued a special announcement. The difference was that it only stated that the metal laboratory project had achieved the expected goals.

This kind of announcement has almost no impact at all, and even people in this school are not interested in taking a look at it.

However, someone noticed.

Donggang University, Alloy Materials Laboratory.

Ma Wenjun has been paying attention to the developments of the New Metal Materials Technology Research Institute and the Aerospace Materials Institute.

Although his judgment is the same as Chen Jianlin's, he believes that the Institute of Aeronautical Materials has delayed research, and the metal laboratory has limited funds and cannot produce results at all, but when it comes to his own problems, as long as there is a slight possibility, special attention needs to be paid.

one time.

When he saw the announcement issued by Xijing Jiaotong University, Ma Wenjun felt incredible and panicked to the extreme. He immediately found Chen Jianlin.

After Chen Jianlin heard Ma Wenjun's words, he was a little panicked. He quickly checked the message, then picked up the phone to inquire and learned the details of the results.

"Peng Hui's team has developed conventional methods to manufacture titanium alloys with a tensile strength of 1,400 MPa."

"This parameter... is not bad!"

Chen Jianlin breathed a sigh of relief when he knew the result.

The tensile strength of the world's top TB titanium alloy can exceed 1200 MPa, and some even exceed 1400 MPa.

This data does not deviate from the scope of ‘conventional’. Even if it is studied, it cannot explain the problem accurately.

There are many factors that affect the strength of titanium alloys, including element ratios, manufacturing processes, and technical means. Removing impurities to make the purity of titanium high enough is also one of the important means.

R&D results and manufacturing processes within the 'conventional' range may not necessarily tend to be standard, or they may just be 'lucky'.

It's like a group of people running in a clueless running race. They don't know which direction is correct, but only one is the correct direction.

After the running time is up, you can only know the distance moved in the correct direction.

Some people ran 100 meters in one minute, and some people ran 150 meters in the same time.

These are all normal numerical ranges, and there is no way to rely on running distance to determine the correct direction.

However, if someone runs two hundred or three hundred meters in one minute, to a certain extent, it can be determined that the direction in which he ran is very close to the correct direction.

The metal laboratory used conventional methods to produce a titanium alloy with a tensile strength of 1,400 MPa. It may be just luck and not sure that the research is in the right direction.

Naturally, comparison of experimental data cannot fully explain the problem.

However, if a titanium alloy with a tensile strength of 1500 MPa, 1600 MPa, or even higher is manufactured, the situation will be completely different.

"Peng Hui, you are really quite capable. I underestimated him."

Chen Jianlin sighed with emotion and continued, "Professor Ma, at least we no longer have to worry about the metal laboratory. They have submitted the results and the project is almost over. We can rest assured."

Ma Wenjun put his mind at ease, and suddenly felt relaxed all over, and asked, "How is Professor Zhou doing there?"

"Xiaolong."

Chen Jianlin sighed, shook his head and said, "Don't worry about this. I have already told him to go home and rest for a while. After the first six months or one year, I will give him a new job."

"I definitely won't be able to come back to Donggang University, but I can go to other universities as a teaching post. A guy like Wang Hao can go to Xihai University, so I still have some respect."
