Chapter 196 Tungsten, Molybdenum, Tungsten, Copper (3k)

A lady also found it interesting: "Zhonghai, Zhendong's idea seems to be really feasible. Dongxu left this family behind, so we can really help them."

Looking at the old lady, Gao Zhendong suddenly remembered something he had seen in a TV series in his previous life, which put the final straw on Yi Zhonghai's back: "Master Yi, if you are really afraid of gossip, you can add another code."

Yi Zhonghai and the auntie were a little confused: "Add a code?"

Gao Zhendong smiled and said, "If you let Auntie and Qin Huairu become godparents, no one will say a word about this matter. Of course, if the Jia family doesn't want to, then just ignore what I said."

This idea was not something Gao Zhendong came up with himself. It was a brilliant idea that he saw from netizens while watching TV series in his previous life. Because it was very practical, it left a deep impression on Gao Zhendong.

If the Jia family themselves are unwilling, it can also reveal a lot of their family's thoughts. In this way, Yi Zhonghai's family does not have to rush to do this, and it can also cut off Yi Zhonghai's thoughts and find another way, which may not be a bad thing for Yi Zhonghai.

As soon as these words came out, Yi Zhonghai and Auntie's eyes lit up. Auntie looked at Yi Zhonghai and said, "Zhonghai, Zhendong's idea is not bad."

Yi Zhonghai's only concern was about people's mouths, and this method could shut them up completely. Since an aunt adopted her as her goddaughter, she would naturally endorse this matter. If other people still used this to make trouble, the Yi and Jia families would not have to say anything, as others would think she was a worthless person.

Avoiding suspicion before recognizing relatives and binding them together afterwards can be said to solve the immediate problem and eliminate worries.

Yi Zhonghai nodded to the auntie and said, "Go ask Huairu later. If she is willing, then we can do as Zhendong suggests."

Turning around, Yi Zhonghai said to Gao Zhendong: "Zhendong, thank you for this matter. I'll take the matter you mentioned."

For Yi Zhonghai, the outcome on the Jia family's side is not important. What is important is that he can get over this matter.

This is also a good thing for the printer research group of the Institute of Computing. For the production of non-standard parts, an eighth-level fitter is not a cabbage on the roadside that can be easily picked up. Moreover, there are even fewer people like Yi Zhonghai who have participated in scientific research projects and have experience in similar equipment modification.

After solving Yi Zhonghai's problem, Gao Zhendong returned home with a sense of pride. After leaving Yi Zhonghai's house, Gao Zhendong looked to both sides with an amused smile, wondering what kind of interesting things these families would create in the future under the waving of these huge butterfly wings.

The Institute of Computing acted quickly and sent the research plan for the printer 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 became the chief designer. He asked the people in the Operation Institute to make their own decisions as the leader.

The people from the computing institute took the document back. Chief Engineer Chi looked at this biggest change and was a little puzzled: "He won't be the project leader? What did Director Gao say?"

"Director Gao's original words were - I am only providing ideas and principles for this matter. You guys will be responsible for the specific implementation and all the minor matters. It is enough for me to be the chief designer. I will not be in charge of this. You can go back and ask your institute to divide the work according to the facts and report it truthfully."

Chief Engineer Chi shook his head and said with emotion: "Director Gao is really not competitive at all. He is a man of high moral character and is worthy of admiration."

The comrade with the documents laughed and said, "Maybe he has too many achievements, so he doesn't like this stuff, haha."

Chief Engineer Chi smiled and said, "Whether he likes it or not is one thing, whether he is willing to let it go is another. But you are right, he really doesn't need this little bit of achievement, so we accept his kindness. You put the file aside for now, and I will discuss this matter with Director Li."

The comrade with the documents took out another list: "These are the comrades responsible for mechanical design and processing that Director Gao coordinated for us. They need to be included in the plan when the time comes."

Chief Engineer Chi took it and looked at it. There were several people listed on the list, each with a brief introduction. He was very satisfied with the first person on the list.

——Yi Zhonghai, an eighth-level fitter at the Third Steel Rolling Mill, has scientific research experience in the development of thermocouples and was responsible for the modification of the JP-59 keyboard prototype.

"Wow, Director Gao's work is really extraordinary. Look at this person, he is perfect for the printer development work, and he is also an eighth-level fitter. It is not easy to find or borrow him."

Finding it is one problem, whether you can 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 him, or may not even bother to persuade him.

Gao Zhendong himself was arranging things for a few people, who were responsible for the trial-production of several special materials funded jointly by the 17th Ministry of Machine Building and the factory.

"Engineer Liang, the alloy ratio of tungsten to molybdenum is 50:50. After you make it, process it according to the given drawings, and then send it to the Northeast Carbon Research Institute together with the graphite backing processing requirements. Ask them to process the graphite backing and do the test."

Liang Faming wrote it down, and then asked, "Director Gao, what about the other two alloys?"

Gao Zhendong smiled and said, "Although these two look like two metals combined together, they are not really alloys. They are pseudo-alloys. If they can become alloys, we won't make these two materials. We want the property that they cannot become alloys." These two are tungsten-copper materials. The reason there are two of them is because the amount of copper infiltration inside is different, one is about 3% higher than the other.

Don't underestimate this 3%, it will cause a huge difference in tensile strength and toughness under high temperature conditions.

Simply put, one has greater tensile strength and the other has better toughness.

As for tungsten silver, since its application coverage is not as wide as tungsten copper, Gao Zhendong is not planning 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 and high temperature, good anti-adhesion and plasticity, and low volume expansion coefficient.

Except for some individual properties that are slightly worse than tungsten silver materials, such as electrical conductivity and thermal conductivity, other properties and usage directions of tungsten silver are fully covered. It has more advantages than tungsten silver and can be widely used in electronics, aerospace, military and other fields.

From the perspective of trial-producing new materials under limited conditions, tungsten copper has a higher cost-effectiveness than tungsten silver. However, some individual properties of tungsten silver are more outstanding, which can be discussed later.

Gao Zhendong went on to say: "The process routes for these two materials are the same: isostatic pressing of tungsten powder, high-temperature sintering to form a tungsten skeleton, infiltration of copper, and then mechanical processing to obtain the finished product."

This process is not a problem for Liang Faming and his team.

"You should pay attention to the particle size of tungsten powder, xx microns is better."

"At the same time, you should also take a batch of materials and conduct a comparative test using the process of directly mixing tungsten and copper powders in proportion, pressing and forming, and directly sintering."

"After the final specimen has been tested for basic mechanical properties using the test method I gave you, it will be sent to the Institute of Guidance and Research for testing, along with the test results."

Tungsten copper has nothing to do with graphite, and graphite backing is not considered for the time being. Graphite backing provides thermal conductivity, but for tungsten copper materials, it is a bit superfluous for the time being.

Therefore, there is no need to send it to the Northeast Carbon Research Institute, you can send it directly to the Beijing Research Institute.

Liang Faming and his team accepted the task and went straight to work.

Gao Zhendong himself continued to struggle with the operating system and networking programs.

For technicians who have reached a certain level, or for everyone, this is their daily routine. They are always switching between different projects and cannot focus on any one project.

Fortunately, I have basically finished several books, except for the big book that serves as a work manual, as well as "Principles of Automatic Control" and "Design and Manufacturing of Integrated Circuits". Otherwise, I would have been even busier.

What Gao Zhendong is doing now is the implementation of the telnet protocol and the compilation of the telnet server program and terminal program.

The first thing is included in the next two things.

The reason why we need to implement this thing first is that the transmission of messages is actually just incidental. The biggest reason is that the complete implementation of this protocol can provide the function of remote login, which provides a protocol basis for future remote terminal applications.

Otherwise, Gao Zhendong could have written a program specifically for message communication, which would have been much simpler.

Of course, since the original TCP/IP protocol under telnet is not currently in the implementation plan, this telnet is actually a bit lame, but it is not unusable. During the programming process, Gao Zhendong left enough interfaces and extensibility, so it will be convenient to expand it in the future.

Gao Zhendong did not modify the command name definition in telnet, and still defined the commands according to the original English abbreviations, such as EOF (End Of File) and EOR (End Of Record).

After all, these are things that people want to gain technical discourse power after making them public, but they are just closed in their own circles. People don’t understand them and don’t use them, so there is no way they can gain technical discourse power.

In Gao Zhendong's previous life, the Japanese were playing with information technology behind closed doors. As a result, their information electronic consumer products basically did not make any splash in the world, except for a few branches such as self-developed products and games.

It is not uncommon for excellent technologies to be completely abandoned or become useless because no one uses them.

Judging from future developments, it is an indisputable fact that the opponent has the advantage in this round.

When doing things, we must seek truth from facts, take advantage of the situation, and do not act recklessly.
