Material manufacturing, to find a professional.

The manufacture of granular materials involves metal precision machining technology, and Wang Hao found Yang Yunhe, the top Seiko expert in China, and academicians.

Yang Yunhe is an academician of the Chinese Academy of Engineering.

He is a graduate of Harvard University with a degree in materials engineering, holds a Ph.D. in mechanical and materials engineering, has received the Alfred Sloan Prize, the Science Foundation Waterman Fellowship, and is a tenured professor at the University of California, Berkeley.

Later, Yang Yunhe decided to return to China for development, serving as the dean of the School of Physical Science and Technology of Donggang University, and was elected as an academician of the Academy of Engineering during his tenure.

After leaving Donggang University, Yang Yunhe joined the top precision industry company in China, "Donggong Precision", focusing on the research of improving and upgrading metal-related manufacturing technology.

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, and in the small room on the side, he waited for Yang Yunhe, who came to attend the meeting.

Yang Yunhe was very enthusiastic when he saw Wang Hao, he came over to shake hands and said, "Teacher Xu called me. I didn't expect at all, Academician Wang, that you would come here in person. ”

"You're welcome."

Wang Hao greeted him and said, "I can't help it, I'm too anxious to research." In the field of domestic precision industry, Donggong Precision is the most cutting-edge, Academician Yang, you are the top expert. ”

Yang Yunhe was no longer modest, and asked directly, "What are the specific needs?" ”

Wang Hao took out the drawing and pointed to the granular image drawn on it, "I want to ask, with Donggong's precise technical ability, how small can this shape of metal material be?" ”

Yang Yunhe took the drawings and looked at them, frowned and asked, "Do you require high accuracy?" ”

Wang Hao thought for a while and said, "We don't require high precision, but the overall deviation can't be too large, we want to make such metal particles." ”

“…… One millimeter bar. ”

Yang Yunhe hesitated for a moment and continued, "The difficulty in making this shape lies in the semicircular depression of the three faces below, as well as the semicircular bulge above. ”

"The first thing to do is to design the model, but if it's too small, there will definitely be errors."

"If it's lower, you need to study the solution, and it may not just be pure metal physical cutting manufacturing."

He paused as he spoke, thought about it and continued, "Academician Wang, you should know about chips, right?" I'm not saying that we need to make tiny particles at the nanoscale, but because of the complexity of the morphology, we need a similar technology to make particles that are smaller than the millimeter scale. ”

"This is not something that can be done directly, and a systematic system needs to be improved."

Yang Yunhe explained a lot of things in a row.

Wang Hao thought about it and said, "That is to say, if you make particles larger than millimeters, you can directly produce them by designing, but if you are small, it will be difficult, right?" ”

Yang Yunhe nodded, "No matter how small it is, it is not simply cut and molded." ”

"Of course, if you don't do research at any cost, you can find a way to make finer particles, but it takes a lot of investment and time."

Wang Hao has a score in his heart.

……

The answer given by Yang Yunhe was even better than expected.

Wang Hao thought that millimeter-level particles were difficult to manufacture, after all, the shape of the particles on the drawings was too complex.

For now, millimeters are enough for the time being.

He chatted with Yang Yunhe again, and knew that the other party still had to attend the meeting, so he didn't continue to bother, but 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 Navitas Materials Laboratory to find 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 to see Wang Hao, and came out after explaining a few words to others.

"Academician Wang, you're here!"

Xia Guobin greeted and immediately said, "Our research has not found anything recently. ”

There was a sourness in his voice.

Before Wang Hao came to talk about the research problem, he also felt that the asking price of five million was too high, so it was automatically reduced to four million.

Later, I learned that the other party had prepared 20 million.

Twenty million turned into four million, and it felt like a stab in the heart.

Wang Hao didn't care about Xia Guobin's tone, but said, "It's not for the project, I came this time to ask a question." ”

"What?"

Xia Guobin's expectation suddenly turned into confusion, and he couldn't think of any questions Wang Hao would ask himself.

Wang Hao took out the drawings of the particle scheme, spread them on the table and said, "Professor Xia, look at this three-dimensional figure, it is a thirteen-sided figure, with a semicircle of one face protruding above and three small semicircles concave below. ”

"Uh-huh."

Xia Guobin nodded while watching.

"You're an expert in nanomaterials, is there a way to make micron-sized metal particles like this?"

“——？”

Xia Guobin was stunned with his mouth half-open.

It took him a long time to react before he seemed to come back to his senses, and asked rhetorically with an exaggerated expression, "Micron? Such a complex structure? ”

"yes?"

Xia Guobin pursed his lips vigorously.

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 did?" ”

“…… Bead separation? ”

"Yes!"

Xia Guobin nodded vigorously, "At that time, we cooperated with Chuangwei Group to study the separation of micron-level conductive microspheres, and the manufacture of those conductive microspheres, simply understood, is heating, stirring, separation, ......."

"Micron-sized metal balls can only be made by such a simple method, and the figure you take out is so complex that it needs to be finely cut at the centimeter level......"

Needless to say, the follow-up.

Xia Guobin's face was loveless, and his expression seemed to say, 'Are you kidding me?'.

Wang Hao also began to be silent.

He pursed his lips and frowned in thought, and after more than a minute, he suddenly spoke, "Microsphere Manufacturing...... Tell me more about it. ”

"You ask this?"

"That's right."

"Academician Wang, are you not kidding me?"

"Of course!"

“…… 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 material is placed in a molten metal liquid and broken up by physical means, it will naturally separate into fine balls.

When the surface of the ball is contaminated with metal, it has the property of conducting electricity.

This process makes use of material properties.

On the way to the Annihilation Force Field Experimental Base, Wang Hao's mind kept thinking about the process that Xia Guobin said, and he felt that there was some commonality between the manufacture of microspheres and granular materials.

Microsphere manufacturing takes advantage of the physical properties of materials;

During the process of conduction, a semi-topological structure is formed inside the material, which is also a microscopic physical property.

If you can create a strong voltage environment and place the melted metal material in it, as long as there is a sufficient strength of current passing through it, the melted metal material will also form a semi-topological structure.

In this state, can metal particles similar to semi-topology be separated by some physical means?

"The granular design is designed according to the layout of the material that excites the anti-gravity force, but in essence, it is infinitely close to the semi-topological structure inside the conductor."

"Semi-topology is a physical property, which is related to the ion lattice, but is not exactly the same, and can be considered as an extrusible bond structure......"

"In the superconducting state, the semi-topology is flattened, allowing a large number of electrons to pass through unhindered, and from this point of view, the semi-topology imposes some kind of restriction on the activity of electrons......"

"Then in the special high-voltage environment, the semi-topological structure and external physical interference may also produce some kind of continuous ......"

Wang Hao thought about it carefully, and finally decided, "This technique must be difficult. But if you want to make granular materials in the micron range, this could be a good direction. ”

He has already arrived at the experimental base.

The purpose of this visit to the experimental base is to conduct a direct current anti-gravity measurement experiment of materials.

DC anti-gravity and AC anti-gravity are different.

At present, the annihilation force field experimental group has mastered four oblivion force field techniques, one is the conventional AC anti-gravity technology, that is, to create an upward anti-gravity field.

This technique has been classified as a 'basic technology' and is only used to determine the anti-gravity properties of materials.

The second is the AC lateral anti-gravity technology, which is used by the air-ship series of aircraft.

The third is the DC anti-gravity technology, which is an improvement of the F-ray technology, which can use a device and then rely on the spiral magnetic field to extrude 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, because the metal materials cannot excite the annihilation force field characteristics in the superconducting state.

The current DC anti-gravity measurement experiment is to determine whether superconducting materials containing first-order iron, first-order lithium, and with conventional anti-gravity characteristics have DC anti-gravity characteristics.

Wang Hao had already contacted Liao Jianguo in advance, 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've been waiting for a day.

"Academician Wang, you're 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's really looking forward to it.

Wang Hao nodded, "There are several materials with anti-gravity properties, and we want to use them to try to create a DC anti-gravity field." ”

"That's great!"

Liao Jianguo looked forward to it, "If we can replace high-pressure hybrid materials, F-ray excitation will become easier, and there will be more room for improvement." ”

"Most importantly, metal materials can greatly improve the stability of the equipment."

Tang Jianjun immediately added, "In this way, we can use the relevant technology to make a vessel for nuclear fusion reactions." ”

“……”

Liao Jianguo looked at Tang Jianjun but didn't want to speak, he felt that this old guy had 'defected'.

When the F-ray experimental group was first established, Tang Jianjun took the initiative to apply to join it, with the purpose of understanding the relevant technology and seeing if he could develop and research nuclear fusion technology.

Tang Jianjun is the top NMR expert, and his personal research field is just right, even if it is the F-ray experimental group, it is not easy to recruit such experts.

Liao Jianguo naturally felt very happy.

Outcome......

When it was discovered that the research of the Annihilation Force Field Experimental Base had the hope of creating a container for controlling nuclear fusion, Tang Jianjun stayed at the experimental base for a long time, and even more excessively, he also helped people move the hard mattress that he was used to sleeping on.

Isn't that just not going back?

Liu Yunli stood aside and smiled, but he felt that Tang Jianjun's approach was not wrong.

Although Liao Jianguo has a good relationship with him, and he has complained about the undisciplined and unprincipled academician Tang Lao, from the perspective of technology research and development capabilities, the Annihilation Force Field Experimental Base has the hope of making leaps and bounds in technology.

The F-ray experimental group also has a role, but no matter how much research is conducted, it will only make small improvements and enhancements to the technology.

Now the team is still here to participate in the experimental research.

That's the proof.

Wang Hao and Liao Jianguo exchanged a few words, and then went to check the materials used in the experiment together.

There are seven types of materials in total.

Among them, FCW-031 has the highest anti-gravity characteristics, and it also includes FCW-025, FCW-028, FCW-041, etc., which are all superconducting materials containing first-order iron elements.

FCW-025 is also special in that it contains first-order lithium and is the only material that contains first-order iron-lithium dual elements.

After checking several materials together and discussing a few words about the experiment, Liao Jianguo walked out of the door and asked Wang Hao, "Academician Wang, do you think that among these materials, can you find a material with DC anti-gravity characteristics?" ”

A group of people all looked at Wang Hao.

Wang Hao hesitated and said, "I'm not sure, there may be one or two?" Hopefully you'll find out. He shook his head vigorously as he spoke, showing a look of helplessness.

Then, walked away.

Liao Jianguo was suddenly a little disappointed, "Even Academician Wang is not sure, it seems that ...... Not much hope! ”

"Yes...... Yes? ”

Tang Jianjun was about to agree, but suddenly remembered the previous two experiments and what Xiang Qiansheng said to him.

So he decided not to give an opinion.

Liu Yunli said with a smile, "With my understanding of Academician Wang, since he said that there may be one or two, there is great hope." ”

"Why?"

Liao Jianguo looked at it incomprehensibly.

Liu Yunli explained, "Academician Wang just can't be sure, but he is definitely still confident, and he said 'there are one or two', not 'one is good'." ”

"Notice the difference!"

"I said that, do you understand?"

“……”

“……”

Liao Jianguo and Tang Jianjun were silent together, they didn't know what to say, but how could they pay attention to the difference in words in their daily speech.

Liao Jianguo pursed his lips vigorously, patted Liu Yunli's shoulder for a long time, sighed and said, "How do I feel, Academician Wang is like the emperor, and you people are like courtiers who pat the emperor's ass, and you have studied the rules of the emperor's speech." ”

"Really...... It's so professional! ”

There was sarcasm in his voice.

Tang Jianjun nodded in support, and he thought that Xiang Qiansheng felt the same way.

"I didn't mean to figure it out!"

This time it was Liu Yunli's turn to sigh.

There was some sadness in his voice, and he said with a wry smile on his face, "This is a rule that has been hit too many times and his mood has risen and fallen too many times, and then he has summed it up......"
