Rule department scholar

Zhao Yi and Fan Lei continued to sigh with emotion, "It's really beautiful!"

"Yes!"

The two looked back together.

Li Renzhe, who is somewhat thin, and Huang Wenqian, who is short and round, ran slowly together, forming a picture with sharp contrast, it is really...

"This is love!"

"Yes, love!"

Fan Lei said seriously, "I don't understand Lao Li's love. I really envy him. He is so happy. I have decided that I must find someone with a good figure and good looks..."

"come on!"

……

The next morning, Zhao Yi went to the Metal Materials Laboratory of Capital University of Aeronautics and Astronautics.

The last time I came here was for a meeting, and a large group of people went to visit it. It was lively and lively, but it was a bit official.

This time I came alone, the situation is different, and the mentality is also different.

When Zhao Yi arrived at the University of Aeronautics and Astronautics, he was still in the mood to stroll around the campus. After a long walk, he went to the material laboratory. Follow and walk out.

"Zhao Yi, here we come, welcome, welcome!" The old professor enthusiastically shook hands.

"This is Professor Xu!" Zhang Hongtao introduced.

"Professor Xu, hello."

Professor Xu said, "I heard from Hong Tao yesterday that you are coming here, and I am looking forward to it! I heard that you are here to help Hong Tao look at the research?"

"It's not about the project. I'm not that talented. I really don't know anything about chemistry and materials science. Professor Zhang called me. It just so happened that today is the weekend, so I came to study."

"It's really modest!" Professor Xu led Zhao Yi in after speaking.

Professor Xu and Zhang Hongtao are in the same workshop, and they can be regarded as half of Zhang Hongtao's teacher. They always call Zhang Hongtao by his first name.

After entering the workshop, Professor Xu went to work on his own affairs, while Zhang Hongtao took Zhao Yi to look at the research materials, which were all related to alloy plates, as well as the contents and reports of the experiments carried out.

Zhao Yi carefully looked at the content line by line, and in some places there were professional terms, which he could not understand at all. He asked, "Do you have the most basic information? For example, the properties of elements such as titanium and aluminum. ..."

These basic data are more important.

Zhang Hongtao was a little surprised when he heard that, so he went to the computer to find some materials, and even helped to print them out and hand them to Zhao Yi.

Zhao Yi flipped through it quickly, and went to the workshop with Zhang Hongtao.

At this time, Zhang Hongtao didn't have any hope. He originally thought that Zhao Yi knew a lot, but he didn't even know the nature of the elements. It was really strange how he could help.

"I really don't understand anything."

Zhang Hongtao thought a little depressed, but he didn't feel anything. In fact, it was quite normal. The other party was an expert in mathematics and computer, and also dabbled in biomedicine. He had never heard of chemistry.

He simply thought that the other party was here to visit. It felt pretty good to have a top mathematician visit the laboratory.

Zhao Yi followed Zhang Hongtao inside and arrived at the place where he was doing research. He saw the titanium alloy plate he saw last time.

A large piece of the plate is obviously missing, and it must have been used up during the research.

Zhang Hongtao thought that Zhao Yi was here to visit, so he began to explain, "After cutting and dissolving the plate, we carried out detailed calculations on the composition, and the first thing we got was the content of titanium."

"This is easy to measure. After dissolution, use inert gas..."

"Ula Ula..."

Zhang Hongtao talked about a lot of knowledge about professional methods, but he couldn't understand it at all.

Zhao Yi simply interrupted, "70.00% three point five?"

"……what?"

"Aren't you talking about the titanium content?" Zhao Yi explained.

Zhang Hongtao looked down at the document in his hand, and checked the numbers carefully. Of course he knew what Zhao Yi said was right, but he didn't know how the other party knew.

73.5%?

That's right!

Zhang Hongtao really wanted to ask, but he still didn't ask, but continued, "That's right, it's indeed 73.5%. Later, it was determined that it was aluminum and magnesium, and aluminum-magnesium alloys are the most commonly used..."

"Ula Ula..."

Zhao Yi's head was a little dizzy, and he couldn't help but interrupted again, "Are you talking about the content of aluminum and magnesium? I think it should be between 13.00% and 17.00%. I'm not sure what the value is, but it should be about the same .”

Of course he knew the exact value.

The board is right in front of you.

As long as you use the "correlation rate" to check the relationship between the plate and aluminum and magnesium elements, the content will come out directly.

But you still have to keep a low profile, just 'estimate' a number.

Zhang Hongtao stared blankly at Zhao Yi, thought about it carefully, and felt that he understood, "It seems that you know a lot about alloys. The ratio of aluminum-magnesium alloys is regular and can be found. If the content varies too much, it may not be possible to build a uniform system..."

"Ula Ula..."

Zhang Hongtao continued talking for a long time, explaining why Zhao Yi could directly know the content, which made Zhao Yi feel speechless.

What else to say?

The other party explained it directly!

Zhang Hongtao finally changed the topic, went to the side of a smelting machine, took out a small piece of silver-white metal, "Look at this..."

Zhao Yi took it over and took a look, "Titanium alloy? It also contains aluminum, magnesium, and carbon, right? And that titanium alloy plate..."

"This is what we got."

Zhang Hongtao said proudly, and then asked Zhao Yi, "Can you see the difference between this piece and that piece?"

"The difference... the color is a bit different." Zhao Yi looked carefully, and subconsciously used the "Correlation Rate" to compare the two plates together, "This one is brighter, it should have less carbon content? Aluminum-magnesium The ratio is also different, and there are no rare elements added.”

"That's right!"

Zhang Hongtao took a deep breath, and looked at Zhao Yi in disbelief, "Can you infer so much from the color?"

"Guess, wild guess."

Zhao Yi laughed and said, "I really don't understand these things."

"..."

Zhang Hongtao suddenly had a feeling of being fooled.

Chapter 297 The Significance of the National Level

Zhang Hongtao didn't know how to react, looking at Zhao Yi with an 'apology smile', he really felt cheated.

That piece of titanium alloy plate with very high technical content, the content of various elements is known directly?

How did you know?

"Could it be that he has read the materials? Impossible. I am the only one doing this research, and it is difficult to find a second piece of materials in China."

This thing is certain.

Zhang Hongtao is just a researcher, but he also knows the preciousness of titanium alloy plates. The use of each titanium alloy plate imported from abroad will be supervised by a commissioner sent from abroad, and it must not be used for experimental research.

Although there are many ways to cut off a piece of material, the material is very precious and limited, and not much can be used on a satellite. Cutting out a small piece is worth a lot. Using such a large piece of material for research, the domestic There is a high probability that this is the only one.

"Or, he knows foreign experts in material science, and they also know this kind of board?" He wondered.

There is this possibility.

The circle of friends is divided into grades, which grade will have the kind of contacts and circles of friends. Zhao Yi is a top scholar in the world, and he knows a top material expert. He has specifically asked questions about satellite titanium alloy plates. no big deal.

Another point is even more unclear.

The titanium alloy synthesized in the laboratory, which is very close to the material plate, can tell the difference from the original plate at a glance?

"Guess what?"

"Is it really possible to guess just by guessing?"

"Less carbon element, no neptunium...Indeed, if it is for analysis, if carbon is missing, other elements must be added. It is best to increase the original elements. The most suitable ratio can be calculated... "

"In other words, he completed the calculation in a very short time..."

"However, I calculated for a long time. It took about half a month before I tried out the most suitable ratio."

"He is a top mathematician, with strong mathematical ability and fast calculation speed?"

Zhang Hongtao thought about it for a long time, but he could only reluctantly come to this seemingly acceptable conclusion, because he couldn't think of other possibilities.

Zhang Hongtao looked at Zhao Yi again and took a deep breath. Instead of asking why the other party knew, he got into the topic, "This is the result of my research."

He gently picked up the imitation titanium alloy plate, and sighed deeply, "The work I've been doing recently is trying to add metal neptunium to it, but no matter how I change the ratio, I can't succeed." , and even got powdered waste once."

Zhao Yi didn't understand a lot, and didn't know what to say, so he simply asked, "How did you add it?"

"I tried three methods."

Zhang Hongtao explained carefully, "The first one is to grind it into powder, add it according to the proportion, and then smelt it. Of course, it will definitely fail. If it is so simple and it can be successful, there is no need to specialize in research."

Zhao Yi listened and nodded.

"The second is high-temperature and high-pressure smelting. It is forced to enter in a liquid state. Normally, at a high temperature of a thousand degrees higher than the melting point, the elements will be very active..."

Zhang Hongtao's serious and detailed explanation made Zhao Yi's head hurt, but he still resisted the 'do not understand' and continued to stop.

This probably represents respect.

"The last is the furnace gas injection, which is heated to a very high state, like electroplating, electroplating, you know?"

"This is the hardest way, but you end up with powder waste..."

Zhang Hongtao sighed again.

Zhao Yi listened and nodded, frowning as if he was thinking. In fact, he found that he had obtained enough conditions to use the "Contact Rate".

"Probably related to the third method?" Zhao Yi thought about using "Contact Rate".

system hint--

[Using "Contact Rate" requires 43 energy points, do you want to use it? 】

【use! 】

Zhao Yi glanced at the value of energy consumption, chose 'Use' without hesitation, and immediately picked up the learning coins.

Suddenly, the manufacturing process of titanium alloy plates appeared in my mind, and the information reflected in my mind was very simple, such as the text description of the process, and the content could be understood clearly.

It's easy now.

Zhao Yi let out a long breath, with a smile on his face, and said, "I think the third method you mentioned is actually very close, and the final product is powder, which does not necessarily mean failure, but may mean failure. close to success."

"It's darkest before the dawn, and maybe it's just before the dawn."

"Really?" Zhang Hongtao's eyes lit up when he heard it, not because he was encouraged by Zhao Yi, but because he didn't want to give up the third method.

That was the most reasonable method he could think of.

He thought about it and asked, "Do you have any suggestions for improvement?"

"I don't know much about material science, and I have basically never dabbled in it." Zhao Yi first reminded, "If what I said seems childish and unprofessional, don't laugh at me."

"No, no." Zhang Hongtao waved his hands again and again. Now he doesn't believe what Zhao Yi said about "do not understand".

It's all like this, still don't understand?

Too modest!

Zhao Yi didn't pay attention to Zhang Hongtao's thoughts, and continued, "Have you ever thought that you can press some kind of gas and metal neptunium together? Under high temperature and high pressure, the gas is very active."

"After everything is pressed in, the temperature and pressure can be lowered, and some means can be used to separate the gas elements."

"Maybe this can make the distribution of elements more even?" Zhao Yi said that he was not sure, he only had a simple manufacturing process in his mind, and there was no explanation for the manufacturing process.

What is the principle?

do not know.

Why do this?

do not know.
