Du Hai, a researcher in the technical laboratory who is responsible for testing, came out a few steps later than Yue Zhiquan. Unlike Yue Zhiquan who pretended to be calm, Du Hai walked out quickly, excitement and excitement clearly written on his face.
"How's it going, Du Hai? What's the tensile strength value?" Peng Hui saw Du Hai and immediately asked again, fearing that Yue Zhi was all joking.
Du Hai clutched his head tightly, his whole face collapsed, and his excitement was palpable. He took a deep breath before saying, "The tensile strength is in the range of 1787 MPa to 1796 MPa."
"That's around 1790, right?"
"Yes, yes, yes, yes..." Du Hai nodded continuously to confirm.
The entire corridor suddenly became more lively.
When Yue Zhiquan said it just now, some people thought he might be joking. The value of 1790 is really amazing, so amazing that people can't believe it. It feels like the data is very false.
Now Du Hai's confirmation has made everyone believe it.
"1790, my God, I don't even know what this is!"
"Is it really 1,790? Isn't there something wrong with the detection? This value should be higher than the highest in the world, right?"
"I remember the highest value was 1720, and it was made by special means."
"We actually made such a high-end titanium alloy..."
Everyone in the Metal Laboratory is very excited. The hard work has been rewarded with huge rewards, so rich that it even seems like a dream.
Peng Hui hugged the others excitedly, and walked quickly towards Wang Hao, hugged him, and shouted excitedly, "Thank you! Thank you! Professor Wang Hao, your analysis is really amazing."
"Without you we wouldn't have been able to complete the initial research, and now this result far exceeds expectations."
"I don't even know what to say now, thank you very much..."
Peng Hui was so excited that he shed tears, and others around him also shed tears of excitement.
They were simply too excited.
At the stairs next to them, Li Jiping and Cao Dongming stood there together. They didn't say a word, with disbelief written on their faces.
Yue Zhiquan also walked over and kept saying excitedly, "When I saw that piece of alloy just now, I knew it was something special. I couldn't help but go in and check it out."
"It's really extraordinary!"
"During the test, I was surprised when I saw the value exceeded 1,600. As a result, I saw that the value slowly exceeded 1,700 and even approached 1,800..."
"You don't know that I was nervous at that time. I was really nervous. I have been doing this for many years and I have never been so nervous or excited."
Yue Zhiquan specializes in material testing. Material testing is also a research direction. Various professional numerical values are used to evaluate material properties. The testing of alloy materials is a general direction.
For professionals like Yue Zhiquan who are related to material composition and performance, doing an alloy testing that surpasses the most advanced international level is simply a dreamlike experience.
It may be difficult for people in other fields to understand Yue Zhiquan's feelings, but they still have an understanding of data.
Li Jiping asked continuously, "How is this possible? 1790? Lao Yue, you are not joking, right?"
"How could I possibly joke about something like this?"
"Isn't this value too outrageous? Last time it was 1560, but this time it was directly increased to 1790?"
Looking at the excited celebration on the other side entering the laboratory, and thinking about Yue Zhiquan's affirmative tone, Li Jiping also knew that the data was real, but precisely because of the reality of the data, he felt that it was completely beyond his knowledge of materials research and development.
What he saw was the same as others, that Wang Hao made a professional analysis and directly made modifications to the project process.
Then, the finished product was so greatly improved?
How is this possible!
Li Jiping's face was filled with disbelief. He felt that what was happening in front of him was beyond his understanding.
As an academician in the materials direction of the Academy of Engineering, he has many experiences leading teams to do material research and development. His team also has people who do data analysis, but their analysis results can only provide some reference opinions for the project and truly formulate the process.
The process is handled by experienced personnel.
Past experience has also proven that the most direct way to develop materials is to conduct continuous experiments.
If the temperature is not good, adjust the temperature; if the quenching effect is not satisfactory, adjust the quenching method; if there is a problem with the finished product produced by the process, consider adjusting the process.
etc.
This is also the reason why most people are not optimistic about metal laboratory projects. Because of the lack of corresponding funds, it is difficult to conduct multiple consecutive experiments. How can the number of experiments produce results?
it's good now.
Things beyond cognition happened right in front of him. Wang Hao, who was hired as a data analyst, just did a data analysis and directly made some adjustments to the process and other aspects, and then the strength of the finished product was greatly increased.
In Li Jiping's opinion, this kind of thing is completely incomprehensible.
Cao Dongming also cannot understand it. He is the leading technical expert in the field of titanium alloys. He has led the team to complete many titanium alloy-related material research and development, and has won numerous awards and honors based on these achievements.
He understands that the research and development of titanium alloys also involves constant experiments.
And his team worked hard, constantly burned money to do experiments, accumulated experience and slowly improved, so that they could produce titanium alloy materials at the internationally advanced level.
The results of it?
Wang Hao just did some data analysis, relied on the results, and guided the process in the metal laboratory, which greatly improved the strength of the finished product.
The tensile strength of titanium alloy is increased from 1560 to 1790.
What is this concept?
Even if we conduct hundreds of experiments and burn hundreds of millions of funds, it is impossible to achieve such a big improvement.
Cao Dongming and Li Jiping looked at each other and could see the disbelief in each other's eyes.
They were not only shocked by the process, but also by the results.
What is the concept of beta titanium alloy compressive strength 1790 MPa?
There are foreign laboratories exploring titanium alloy strength improvement technology and creating titanium alloys with a tensile strength of more than 1,700, but they use "unconventional means."
‘Unconventional means’, the first raw materials used are the best, titanium powder with very rare impurities.
This kind of titanium powder has gone through many processes to remove impurities. Titanium itself is not a particularly expensive metal, but the extraction process is very complicated, resulting in the price of titanium as a single element metal becoming very expensive. And titanium that has been extracted from many impurities, on the other hand,
It is no exaggeration to say that its value is comparable to gold.
The performance of the titanium alloy produced by this kind of titanium powder with very low impurity content will of course be much better. The process of making the alloy will also be repeatedly quenched in a vacuum environment. The most cutting-edge technology is also used in other processes.
.
In the simplest example, most of the manufacturing process is completed in a vacuum environment, which is enough to consume a huge amount of money.
After the alloy is manufactured, a surface quenching step is added to make the surface layer of the finished alloy even harder.
The finished titanium alloy produced by this extreme manufacturing method has a tensile strength of more than 1,700 MPa.
The metal laboratory conducts scientific research on pressure-resistant titanium alloys by "conventional means", and the entire manufacturing process adopts "conventional means". "Conventional means" can be widely used for mass production.
If they add the final surface quenching process to the titanium alloy material they produce, the tensile strength will definitely continue to increase, and it will easily exceed 1800 MPa.
The results of this research have gone far beyond the ordinary scope.
On the small side, it is the research and development that has achieved significant results, and the strength of the alloy products produced exceeds the most advanced international level.
Broadly speaking, the research and development results of the project are remarkable, which can greatly increase the domestic understanding of titanium alloys and leapfrog the research and development technology in the application of titanium alloy materials in various industries.
Scientific theory promotes technology.
Even in the field of material manufacturing, related research and development is divided into two aspects: scientific basis and technology. The metal laboratory is doing basic scientific research. They are exploring how to increase the strength of β-type titanium alloys.
The purpose of this research and development is not to create materials that can be directly applied in industry, but to provide scientific reference for the research and development of other titanium alloy materials.
For example, a certain titanium alloy R&D team project specifies the development of a titanium alloy with fixed properties, and they need to improve the strength of the titanium alloy.
How to do it?
They can refer to the metal laboratory project and make certain improvements to the manufacturing process, and the possibility of achieving the goal is very high.
This will save a lot of time and money for many titanium alloy research and development projects.
Cao Dongming felt the deepest feeling. He immediately thought of this issue because he is an expert in titanium alloy research and development and has five titanium alloy projects in progress.
Three of them need to improve the strength of titanium alloys.
One project is an example. They are developing an aircraft landing gear. The aircraft landing gear is fixed and can be made of β-type titanium alloy. The highest requirement for the landing gear is strength.
When the plane lands, the landing gear must withstand huge pressure. If it breaks, it will cause the aircraft to crash and kill people.
Ordinary civil aviation aircraft do not need titanium alloy landing gears, so special steel is enough.
Fighters are different.
If a fighter jet seeks to increase flexibility, load capacity, etc., it must reduce the weight of the fuselage as much as possible.
The landing gear also occupies a certain amount of weight, and it is not light. If it can be replaced with titanium alloy, a great weight reduction effect can be achieved.
"For example, the alloy we just made has a strength of 1790. Maybe if we study and modify it, we can directly use it to make the landing gear of fighter jets, right?"
Cao Dongming sighed and thought, he wished he could immediately understand all the processes and related analysis content.
Obviously, that's impossible.
Even the expert reviewers from the Materials Science Department cannot view all R&D data. Their right is to gain a general understanding and then test the finished product.
As for the specific R&D processes and information, they still need to be submitted to superiors and kept confidential for major projects.
Others who want to view it can only apply later.
…
The metal laboratory was still busy. After everyone was excited, they immediately started finishing the experiment, taking records, reporting, summarizing and other matters.
Several researchers also have to prepare reports, summarize results, etc.
Wang Hao has always been in the laboratory. Because he is the "second person on the results list", he also simply wrote a research report. The other information to be submitted is the completed analysis report.
That's it.
Several people from the expert review team also stayed together until eight o'clock in the evening. They made some simple records and discussed the results settlement issue with Peng Hui before returning to the hotel to rest.
Li Jiping, Cao Dongming and others returned to the hotel together, and happened to meet Ding Zongquan and Lu Daxiang who had returned from their 'travel'.
Ding Zongquan had no shame in going to the laboratory anymore, so he simply took Lu Daxiang with him to walk around Xijing City, waiting to fly back tomorrow.
Li Jiping couldn't say anything about this.
Although Li Jiping is the leader of the expert group, the expert group is not a formal unit. They are all experts invited by the Department of Materials Science of the National Natural Science Foundation of China. They are only responsible for the review of major projects.
During the review process, if the experts do not actively participate, the most they can do is to say that next time there is a major project review, it will be better not to invite them.
Ding Zongquan didn't care whether he went to the laboratory or not. He asked curiously, "What's the result? The experiment should be over, right?"
When he went out for a walk during the day, he and Lu Daxiang also talked for a few words, and both felt that the finished product could not be improved.
Wang Hao's analysis seems to be very professional, but can material research and development be done by analysis?
When Li Jiping saw Ding Zongquan, he just pursed his lips and said nothing. Then he patted Ding Zongquan on the shoulder and walked towards the elevator entrance.
Yue Zhiquan behaved in the same way, patting Ding Zongquan on the shoulder, and then followed Li Jiping's footsteps.
Ding Zongquan had doubts written all over his face, but Lu Daxiang pulled Cao Dongming and asked, "What was the result?"
"1,7,9,0."
Cao Dongming said four numbers, shook his head and walked away.
Lu Daxiang froze on the spot with his mouth half open. He finally understood why several people reacted like this.
Tensile strength 1790!
This is a value that far exceeds the highest international level.
Which team can produce results of this level will definitely be discussed by many people in the circle, including the research and development process, experience, results, awards, etc. Even the details of the research and development and what happened will most likely be spread out.
Ding Zongquan openly questioned Wang Hao, and was directly rebuffed.
There were several researchers, associate researchers from the Metal Laboratory, and several of their expert reviewers present at the time. The matter would almost certainly spread, not necessarily outside the circle, but people within the circle would most likely know about it.
By then, Ding Zongquan will most likely become the laughing stock in the circle, right?
He was not only rebuffed by Xiaonian, but the facts also proved that Xiaonian was very extraordinary. An analysis report could make the project results have a huge breakthrough at the international level.
What would others say?
"Will I be implicated?" Lu Daxiang regretted traveling with Ding Zongquan during the day. When he thought about it carefully, it seemed to have nothing to do with him.
Then he looked at Ding Zongquan, shook his head, sighed and said the number, "Cao Dongming just said, 1790."
"What?"
"1790." Lu Daxiang repeated, sighed again, and quickly went to find Li Jiping to learn about the situation.
It is better for Ding Zongquan to digest this news slowly.
…
Three days later.
The Metal Laboratory submitted a result report to the Materials Science Department of the National Natural Science Foundation of China, which immediately caused a new round of shock.
Even those who knew the news in advance found it incredible when they just saw the introduction of ‘tensile strength 1790 titanium alloy’.
Next comes project review, settlement and other follow-up issues.
Most of the affairs had nothing to do with Wang Hao. The day after completing the experiment, that is, Monday morning, he took a plane back to Xihai.
Before leaving, Peng Hui took him and said a lot of thanks, and also specifically stated that the results would rank him as the 'number one in contribution'.
Cao Dongming pulled Wang Hao and wanted to invite him to join his project.
Wang Hao refused.
The reason why he helped the metal laboratory do data analysis was firstly because of Xia Guobin's face, but also for two other reasons.
One thing is that he has courses in data mining, probability and functional analysis, and he can do related research and development very quickly.
But the semester has entered its final stage.
"Introduction to Mathematical Mining" has ended, and the other two courses only have one week of classes.
In addition, the super-compressive alloy material was a project of the predecessor's "Fall", and he also wanted to participate in research.
Now that the research has been completed, he really has little interest in materials research.
So as for what Peng Hui said about 'results and contributions come first', he was more concerned about whether he could get extra bonuses for reporting results, winning awards, etc...
Even if you are not short of money, it is always good to get a little more.
After returning to Xihai University, Wang Hao suddenly felt much more relaxed. He let go of the pressure of researching a project. At the end of the task, he once again received a thousand teaching coins, so he could do research freely instead of doing nervous analysis.
He first decided with Shuimu University on the time to give a report after the year.
Then he went to class, chatted in the office, and occasionally conducted his own research and development. What he and Cao Dongmin said was true, and he already had ideas for the next step in research and development.
【Task 3】
[R&D Project: Research on Probability of Prime Number Distribution (Difficulty: S).]
[Inspiration value: 55.]
This is the source of the direction. As the inspiration value continues to increase, his ideas gradually improve.
Although I have just found the direction, I still know what to do.
Read a book!
Read the paper!
Wang Hao is preparing to study a new mathematical method to solve some problems related to numerical laws.
New mathematical methods are not easy.
He wasn't in a hurry either.
The inspiration value of 'Task One' is only just over half, and the courses for the new semester have not yet been decided. After the year, I have to go to Shuimu University to give a report, and I still have a lot to do.
I had a lot of free time a few years ago, so it was good to relax and have some rest, and to have the energy to think and study again.
On Friday, the Science Foundation released a major news.
The Natural Science Foundation of China issued an announcement and decided to fund 340 outstanding youth science projects, with a funding of 1.3 million yuan for each project.
This was an announcement and news. Many media immediately reported it and listed the names of all funded young scholars and the projects they applied for.
Wang Hao’s name and the ‘Prime Number Distribution Probability Research’ project he applied for were clearly listed.
