Chapter 196 Tungsten Molybdenum Tungsten Copper (3k)
Auntie also found it interesting: "Zhonghai, Zhendong said this method seems to be really possible. If Dongxu left this family, can he really help? A bunch of people."
Looking at Auntie, Gao Zhendong suddenly remembered an incident from watching a TV series in his previous life, which put the last straw on Yi Zhonghai: "Master Yi, if you really feel that Afraid of gossip, please add another number."
Yi Zhonghai and Auntie were a little confused: "Add a higher number?"
Gao Zhendong said with a smile, "Let Auntie and Qin Huairu recognize each other. As a godmother, no one can say anything about this. Of course, if the Jia family doesn’t want to, just pretend I didn’t say anything.”
This method was not Gao Zhendong's own idea. It was the whimsical ideas of netizens he saw when he was watching TV series in his previous life. Because it was very practical, it left a deep impression on Gao Zhendong.
If the Jia family is not willing to do so, they can also reveal a lot of their family’s thoughts. In this way, the Yi Zhonghai family does not have to rush to do this, and can cut off Yi Zhonghai’s It might not be a bad thing for Yi Zhonghai to think about it and find another way.
As soon as these words came out, Yi Zhonghai and Auntia’s eyes lit up. Auntie looked at Yi Zhonghai: “Zhonghai, Zhendong’s approach is good.”
Yi Zhonghai’s only thing Doubts are on people's mouths, and this method can seal this mouth tightly. If the aunt takes her as her daughter, then she will naturally endorse this matter, and others will have to take it. This kind of talk doesn't need to be said by the Yi family and the Jia family, others will think it's nothing.
Avoiding suspicion before acknowledging relatives, and tying them up after relatives can be said to not only solve urgent needs, but also eliminate worries.
Yi Zhonghai nodded and said to the aunt: "You can ask Huairu later. If she is willing, then follow Zhendong's idea."
Turning his head, Yi Zhonghai said to Gao Zhendong: "Zhendong, Thank you for this matter. I will take the matter you mentioned."
For Yi Zhonghai, what happens to the Jia family is not important, what is important is that he can get out of this matter.
For the printer research team of the Computing Institute, this is also a good thing. For making non-standard parts, level 8 fitters are not just cabbage on the roadside. They can be picked up casually, and There are even fewer people like Yi Zhonghai who have participated in scientific research projects and have experience in similar equipment modifications.
After solving Yi Zhonghai’s matter, Gao Zhendong returned home with a little pride. When he left Yi Zhonghai’s house, Gao Zhendong looked around with an interesting smile. He didn’t know what would happen next. What kind of interesting things can happen to the family under the flapping of the wings of this huge butterfly.
The computing institute acted quickly and sent the printer's research plan to Gao Zhendong for review the next day.
Gao Zhendong did not change too many things. There was only one major modification. He removed himself from the position of leader and changed it to the chief designer. As the leader, he asked people from the computing institute to do their own work. Consider.
The people from the computing office took the file back. Engineer Chi looked at this biggest change and muttered a little bit: "He doesn't want to be the project leader? What did Director Gao say?"
< br>"Director Gao's original words are - I am just providing ideas and principles for this matter. You have to handle the specific implementation and all the minor matters. It is enough for me to appoint a chief designer. This head is not mine. You just need to go back and ask your office to divide the work according to the facts and fill in the report truthfully."
Chief Engineer Chi shook his head and said with emotion: "Director Gao really doesn't claim credit at all, he is worthy of admiration. .”
The comrade who brought the document laughed and said: "Maybe he has too many achievements, and he doesn't like this thing, haha."
Chief Engineer Chi laughed: "It's one thing whether he likes it or not. Whether you are willing to let it go or not is another matter. But you are right, he is indeed not short of this achievement. We will accept his kindness. You can put the documents first. Li and I will discuss this matter. Let’s discuss it with the director.”
The comrade with the document came up with another list: “This is the comrade responsible for mechanical design and processing that Director Gao has coordinated for us. They will need to be added to the plan at that time.”
Chief Engineer Chi took it over and took a look. There were several people in a row on the list, and everyone had a brief introduction. He was very satisfied with the one ranked first.
——Yi Zhonghai, an eighth-level fitter at the No. 3 Steel Rolling Plant, has scientific research experience in the development of thermocouples and was responsible for the modification of the JP-59 keyboard prototype.
"Hey, Director Gao's action is indeed extraordinary. Look at this person. He is perfect for the printer development work. He is also an eighth-level fitter. He is not someone you can find and borrow casually. . ”
Finding it is one problem, being able to borrow it from their unit is another problem, and whether they are willing to come is another problem.
If an eighth-level worker is unwilling to come to support, their unit may not be able to persuade them, and they may not even bother to persuade them.
As for Gao Zhendong himself, he was arranging matters with a few people. They were responsible for the trial production of several special materials jointly funded by the 17th Machinery Department and the factory.
"Gong Liang, the alloy ratio of tungsten to molybdenum is 50:50. After you make it, process it into shape according to the drawings given, and then send it to the Northeast Carbon Research Institute together with the graphite backing processing requirements. Please They machine the graphite backing and do the testing.”
Liang Fafa wrote it down, and then asked: "Director Gao, what about these other two alloys?"
Gao Zhendong smiled and said: "Don't look at these two, they look like two metals combined. , but it’s really not an alloy, it’s a pseudo-alloy. If it could become an alloy, it wouldn’t be made of these two materials. What’s important is that they can’t become alloys. "These two are tungsten copper materials. , the reason why there are two is because the amount of copper infiltration inside is different, one is about 3% higher than the other.
Don’t look at this 3%, which causes a huge difference in tensile strength and toughness under high temperature conditions.
To put it simply, one has greater tensile strength and the other has better toughness.
As for tungsten silver, since its use coverage is not as extensive as that of tungsten copper, Gao Zhendong is not prepared to do it for the time being.
Tungsten copper is not only used in the lining of rocket engines, take a look at its characteristics: good electrical and thermal conductivity, high melting point, hardness and toughness, resistance to burning damage, high temperature resistance, anti-adhesion and good plasticity , the volume expansion coefficient is also low.
Except for some individual properties that are worse than tungsten silver materials, such as electrical and thermal conductivity, the other comprehensive coverage of tungsten silver’s properties and usage directions has more advantages than tungsten silver and can be widely used in electronics. , aerospace, military and other fields.
From the perspective of trial production of new materials under limited conditions, tungsten copper is more cost-effective than tungsten silver, but some individual properties of tungsten silver are more outstanding, which can be discussed in the future.
Gao Zhendong continued: "The process routes for these two materials are the same. Tungsten powder is isostatically pressed, sintered at high temperature to form a tungsten skeleton, copper is infiltrated, and then the finished product is obtained through mechanical processing."
This process is not a problem for Liang Fang and others.
“You should pay attention to the particle size of tungsten powder, x. Let’s do a comparative test on the direct sintering process.”
“After testing the basic mechanical properties using the test method I gave you, send it to the Institute for Testing together with the test results.”
Tungsten copper has nothing to do with graphite, and the graphite backing is not considered for the time being. The graphite backing provides thermal conductivity, but for the tungsten copper material, it is a bit superfluous for the time being.
Therefore, there is no need to send it to the Northeast Carbon Research Institute, just send it directly to the Beijing Institute of Carbon Research.
Liang found that they accepted the task and went straight to start the work.
Gao Zhendong himself continues to struggle with the operating system and networking programs.
For technicians who have reached a certain level, or for all people, this is their daily life. They are always moving around between different projects and cannot be specifically fixed on a certain project.
Fortunately, except for the tome that serves as a work manual and cannot be written, as well as "Principles of Automatic Control" and "Integrated Circuit Design and Manufacturing", they are basically finished. Otherwise it will be even busier.
What Gao Zhendong is doing now is the implementation of the telnet protocol and the preparation of telnet server programs and terminal programs.
The first thing is included in the next two things.
The reason why we need to implement this thing first is that actually transmitting messages is incidental. The biggest reason is that the complete implementation of this protocol can provide the remote login function, which provides a protocol for future remote terminal applications. Base.
Otherwise, Gao Zhendong can write a program specifically for message communication, which is much simpler.
Of course, since the original TCP/IP protocol under telnet is not in the implementation plan for the time being, this makes telnet actually a bit lame, but it is not unusable. Gao Zhendong stayed in the programming process. With enough interfaces and scalability, it will be quite convenient to expand in the future.
Gao Zhendong did not modify the command name definition in telnet, but still defined the command according to the original English abbreviation, such as EOF (EndOfFile, end of file), EOR (EndOfRecord, end of record).
After all, these are all things that I want to gain the right to speak in technology after they are made public. They are just doing it in a closed circle. People don’t understand it at first glance. No need, then the right to speak in technology is also There is no way to start.
In Gao Zhendong’s previous life, he played with information technology behind closed doors. As a result, except for a few branches such as enclosures and games, his information electronic consumer products basically failed to make a splash in the world. .
It is never uncommon for excellent technology to be completely abandoned or become useless because no one uses it.
From the perspective of future development, this is an indisputable fact that the opponent has the advantage.
You still have to seek truth from facts when doing things, make the best use of the situation, and it is not advisable to act recklessly.
