Chapter 420: Micron-level material manufacturing, Liu Yunli: We have been hit too many times!
Material manufacturing requires professionals.
The manufacturing of granular materials involves metal precision processing technology, so Wang Hao found the top precision machining expert in the country, Academician Yang Yunhe.
Yang Yunhe is an academician of the Academy of Engineering.
He graduated from Harvard University with a major in materials engineering. He has dual doctorates in mechanical and materials engineering. He has won the Alfred Sloan Award, the Science Foundation Waterman Award and other honors, and was appointed as a tenured professor at the University of California, Berkeley.
.
Later, Yang Yunhe decided to return to China for development and served as the dean of the School of Physical Science and Technology of Donggang University. During his term, he was elected as an academician of the Academy of Engineering.
After leaving Donggang University, Yang Yunhe joined the country's top precision manufacturing company, Donggong Precision, focusing on research on improving metal-related manufacturing technologies.
Wang Hao's itinerary is still very secretive.
He did not go to the R&D department of Donggong Precision Company, but went to an academic conference venue related to metal manufacturing. In a small room on the side, he waited for Yang Yunhe, who was attending the conference.
Yang Yunhe was very enthusiastic when he saw Wang Hao. He came over to shake hands and said, "Teacher Xu called me. I never expected that, Academician Wang, you would come here in person."
"You're welcome."
Wang Hao exchanged pleasantries and said, "I have no choice but to do research. I am too anxious about research. In the field of domestic precision engineering, Donggong Precision is the most cutting-edge. Academician Yang, you are the top expert."
Yang Yunhe stopped being modest and asked directly, "What are the specific needs?"
Wang Hao took out the drawing and pointed to the grainy image drawn on it, "I would like to ask, with TOG Precision's technical capabilities, how small can a metal material of this shape be made?"
Yang Yunhe took the drawing and looked at it, frowned and asked, "Are the accuracy requirements high?"
Wang Hao thought for a while and said, "It does not require high precision, but the overall deviation cannot be too large. We want to create such metal particles."
"...just a millimeter."
Yang Yunhe hesitated for a moment and continued, "The difficulty in making this shape lies in the semicircular depressions on the lower three sides and the semicircular bulges on the upper side."
"First of all, we need to carry out model design, but because it is too small, errors will definitely occur."
"If it's any lower, we need to research a solution, which may not just be purely physical cutting and manufacturing of metals."
He paused for a moment, then thought about it and continued, "Academician Wang, you should know about chips, right? I'm not talking about making nanometer-sized particles, but because of the complex shape, as long as you make particles smaller than millimeter-sized particles, you can
A similar technology is needed."
"This cannot be done directly. A systematic system needs to be improved."
Yang Yunhe continued to explain everything.
Wang Hao thought about it and said, "In other words, if you are making particles larger than a millimeter, you can design them and produce them directly, but if they are smaller, it will be difficult, right?"
Yang Yunhe nodded, "No matter how small it is, it can't be solved by simply cutting and plasticizing it."
"Of course, if you do specialized research regardless of cost, you can also find ways to produce finer particles, but it will only require a lot of investment and time."
Wang Hao had something in his mind.
…
The answer given by Yang Yunhe was better than expected.
Wang Hao thought that millimeter-sized particles were difficult to produce because the shape of the particles on the drawing was too complex.
For now, millimeters are enough for the time being.
He chatted with Yang Yunhe again, and knowing that the other party was still attending the meeting, he did not continue to disturb him and returned to Xihai University.
Originally, I wanted to go directly to the Annihilation Force Field Experimental Base, but after thinking about it, I simply went to the Nanomaterials Laboratory and found Xia Guobin who was busy.
Xia Guobin is still doing research on the microproperties of superconducting alloys.
When Wang Hao arrived at the laboratory operation room, Xia Guobin was busy in a white coat. He turned his head and saw Wang Hao, said a few words to the others and came out.
"Academician Wang, you are here!"
Xia Guobin greeted him and immediately said, "Our research has not found anything recently."
There was a hint of sadness in his voice.
When Wang Hao came to talk about research issues before, he thought the asking price of five million was too high, so he automatically lowered it to four million.
Later I found out that the other party had prepared 20 million.
Twenty million turned into four million, and it felt like a sharp stab in the heart.
Wang Hao didn't care about Xia Guobin's tone, but said, "It's not about the project. I came here to ask a question."
"What?"
Xia Guobin's expectation suddenly turned into confusion. He couldn't think of any questions that Wang Hao would ask him.
Wang Hao took out the drawings of the particle plan, laid them out on the table and said, "Professor Xia, look at this three-dimensional figure. It is a trihedron. One of the upper faces is semicircularly protruding, and the lower three small faces are semicircularly concave."
"Uh-huh."
Xia Guobin nodded while watching.
"You are an expert in nanomaterials. Is there any way to create micron-sized metal particles with shapes like this?"
"——?"
Xia Guobin was stunned with his mouth half open.
He reacted for a long time before he seemed to come to his senses and asked with an exaggerated expression, "Micrometer level? Such a complex structure?"
"yes?"
Xia Guobin pursed his lips hard.
He was silent for more than ten seconds and then said, "Academician Wang, when you came to Xihai University, do you remember what research we were doing?"
"...Microsphere separation?"
"right!"
Xia Guobin nodded vigorously, "At that time, we cooperated with the Micron Group to study the separation of micron-level conductive microspheres. To simply understand, the manufacturing of those conductive microspheres involves heating, stirring, and separation..."
"Micron-level metal balls can only be made through such a simple method. The pattern you came up with is so complicated that it needs to be finely cut at the centimeter level..."
Needless to say further.
Xia Guobin had a look of despair on his face, and his expression seemed to say, 'Are you kidding me?'
Wang Hao also became silent.
He pursed his lips and frowned, thinking. After more than a minute, he suddenly said, "Microsphere manufacturing...come and talk to me in detail."
This chapter is not over, please click on the next page to continue reading! "You ask this?"
"yes."
"Academician Wang, are you kidding me?"
"certainly!"
"……All right."
…
The manufacturing process of conductive microspheres, just like Xia Guobin’s description, can be simply understood as ‘heating, stirring, and separation’.
When a certain material is placed in molten metal liquid and dispersed by physical means, it will naturally separate into fine balls.
The surface of the ball is contaminated with metal, which makes it conductive.
This process takes advantage of material properties.
On the way to the annihilation force field experimental base, Wang Hao kept thinking about the process mentioned by Xia Guobin. He felt that there was something in common between the manufacturing of microspheres and granular materials.
Microsphere manufacturing takes advantage of material physical properties;
During the conduction process, a semi-topological structure is formed inside the material, which is also a microscopic physical property.
If a strong voltage environment can be created and molten metal material is placed in it, as long as a current of sufficient intensity passes through, semi-topological structures will be formed inside the molten metal material.
In this state, can metal particles similar to the semi-topological structure be separated by some physical means?
"The granular design is designed according to the material layout that stimulates anti-gravity, but in essence, it is infinitely close to the semi-topological structure inside the conductor."
"The semi-topological structure is a physical property that is related to the ion lattice, but it is not exactly the same. It can be considered as a bond structure that can be squeezed..."
"In the superconducting state, the semi-topological structure will be flattened, allowing a large number of electrons to pass through without hindrance. From this perspective, the semi-topological structure will cause some restrictions on electronic activities..."
"Then under special high-voltage environments, semi-topological structures and external physical interference may also produce some kind of continuity..."
Wang Hao thought carefully and finally decided, "This technology is definitely difficult. But if you want to make micron-level granular materials, this may be a good direction."
He has arrived at the experimental base.
The purpose of coming to the experimental base this time is to conduct a DC anti-gravity measurement experiment on materials.
DC anti-gravity and AC anti-gravity are different.
The annihilation force field experimental team now masters four annihilation force field technologies. One is the conventional AC anti-gravity technology, which is to create an upward anti-gravity field.
This technology has been classified as a "basic technology" and can only be used to measure the anti-gravity properties of materials.
The second is to exchange lateral anti-gravity technology. The air-ship series aircraft use lateral anti-gravity technology.
The third type is DC anti-gravity technology. DC anti-gravity technology is an improvement on F-ray technology. It can use a piece of equipment and rely on spiral magnetic field extrusion to create a thin layer of strong annihilation force field to excite F-rays.
Finally, there is the DC strong annihilation force field technology.
The latter two technologies still use high-pressure hybrid materials. The reason is that metal materials cannot stimulate the annihilation force field characteristics in a superconducting state.
The current DC anti-gravity measurement experiment is to determine whether superconducting materials containing first-order iron, first-order lithium and having conventional anti-gravity properties have DC anti-gravity properties.
Wang Hao had contacted Liao Jianguo in advance and asked them to send a technical team over, and asked Liu Yunli to come by name.
After Liao Jianguo got the news, he personally led the team over.
They have been waiting for a day.
"Academician Wang, you are here!"
Liao Jianguo saw Wang Hao's face full of enthusiasm, "What is the new experiment? It is said to be related to metal materials?" He was really looking forward to it.
Wang Hao nodded, "There are several materials with anti-gravity properties. We are going to use them to try to create a DC anti-gravity field."
"That's great!"
Liao Jianguo expects, "If it can replace high-pressure hybrid materials, F-ray excitation will become easier, and there will be greater room for improvement."
"The most important thing is that metal materials can greatly improve the stability of the equipment."
Tang Jianjun immediately added, "In this way, we can use relevant technologies to create containers for nuclear fusion reactions."
"..."
Liao Jianguo looked at Tang Jianjun but didn't want to speak. He felt that this old guy had already 'rebelled'.
When the F-ray experimental group was first established, Tang Jianjun took the initiative to apply to join. The purpose was to learn about relevant technologies and see if nuclear fusion technology could be developed and researched.
Tang Jianjun is the top nuclear magnetic expert, and his personal research field is exactly the same. Even for the F-ray experimental team, it is not easy to recruit such an expert.
Liao Jianguo was naturally very happy.
result……
When it was discovered that research at the annihilation force field experimental base could lead to the creation of a container to control nuclear fusion, Tang Jianjun stayed at the experimental base for a long time and would not leave. What was even more outrageous was that he even asked someone to help move the hard mattress he was used to sleeping on.
Got here.
Doesn’t this mean you won’t go back?
Liu Yunli stood aside and laughed. He felt that Tang Jianjun's approach was not wrong.
Although Liao Jianguo had a good relationship with him, and they both complained about the unruly and unprincipled Academician Tang, from the perspective of technological research and development capabilities, only the Annihilation Force Field Experiment Base can hope to achieve a quantum leap in technology.
The F-ray experimental group is also useful, but no matter how much research is done, it can only make slight improvements and improvements in technology.
Now the team still has to come here to participate in experimental research.
This is clear evidence.
Wang Hao and Liao Jianguo exchanged a few words and then went to check out the materials used in the experiment.
There are seven types of materials in total.
Among them, FCW-031 has the highest anti-gravity properties, and also includes FCW-025, FCW-028, FCW-041, etc., which are all superconducting materials containing first-order iron elements.
FCW-025 is also very special. It contains the first-order lithium element and is the only material containing the first-order iron-lithium dual element.
After checking several materials together and discussing a few words about the experiment, Liao Jianguo walked out and asked Wang Hao, "Academician Wang, do you think any of these materials can be found to have DC anti-gravity properties?"
?”
A group of people looked at Wang Hao.
Wang Hao said hesitantly, "I'm not sure. There may be one or two types? I hope I can find something." He shook his head vigorously as he spoke, showing a look of helplessness.
Then, walked away.
Liao Jianguo was suddenly disappointed, "Even Academician Wang is not sure. It seems... there is not much hope!"
"yes?"
Tang Jianjun was about to express his agreement when he suddenly remembered the two previous experiments and what Xiang Qiansheng said to him.
So he decided not to express his opinion.
Liu Yunli smiled and said, "Based on what I know about Academician Wang, since he said there might be one or two, I have great hope."
"Why?"
Liao Jianguo looked over in confusion.
Liu Yunli explained, "Academician Wang is just not sure, but he is definitely confident, and he said 'one or two', not 'one is good'."
"Notice the difference!"
"I said this, do you understand?"
"..."
"..."
Liao Jianguo and Tang Jianjun were silent together. They didn't know what to say, but they just had to pay attention to the difference in words in daily speech.
Liao Jianguo pursed his lips hard, patted Liu Yunli's shoulder for a long time, sighed and said, "Why do I feel that Academician Wang is like the emperor, and you people are like ministers who flatter the emperor, and you still study The emperor speaks in a regular manner."
"It's... so professional!"
You can hear the sarcasm in his voice.
Tang Jianjun nodded in support, thinking that Xiang Qiansheng had the same feeling.
"I didn't mean to speculate!"
This time it was Liu Yunli's turn to sigh.
There was sadness in his voice, and he said with a wry smile on his face, "This is a rule that I have learned after being hit too many times and having ups and downs in my mood too many times..."
