Although it was my first time here, Qin Zhenhua has been tirelessly studying tanks and firepower in recent years. In order to study advanced armor-piercing technology, of course, he has also studied how to improve the performance of tungsten alloys. However,
After reading some information briefly, he knew that he did not have the ability. This is the gap between experts and scholars and ordinary people.
He can understand the various introductions of popular science, but for real research, it requires immersion in this major for many years. Various smelting technologies and a slight change will bring huge differences in product performance, in addition to the need for
In addition to professional skills, it takes many experiments to accurately find the best combination.
However, being able to see the other party's device at a glance also shows that Qin Zhenhua, an outsider, has actually had a very high professional level, which has also attracted the attention of Mr. Huang.
"We kids have extraordinary vision," said Zhu Lao, "Now, I'm always helping him with work."
The project development of the second-generation tank of the first machine factory actually has nothing to do with Mr. Zhu. Mr. Zhu passed by under Qin Zhenhua's deception, so now he is helping Qin Zhenhua work, and he is not wrong.
Mr. Huang's eyes became even more sharp, and he looked at Qin Zhenhua: "Oh? He is really a talent. So, he is from the Yimai Factory?"
"Yes, I am a worker at the First Machine Factory." Qin Zhenhua said: "Old Huang, if we want to build the most advanced tank, we need technical support from you. How is the performance of the tungsten alloy rod just developed?"
"Yao, it's indeed an expert. After taking a look from the outside, you know it's a tungsten alloy rod. Lao Zhu, did you tell him?" Huang Lao asked with a smile.
"Of course not. The layman watches the fun, and the expert sees the tricks. Our kid has touched a lot of tungsten alloys, so of course he can see it at a glance." Mr. Zhu said.
"Well, what is the performance you want?" Huang Lao did not say what the tungsten alloy he burned out now, but asked Qin Zhenhua what he wanted.
"What we want..." Qin Zhenhua suddenly saw countless data in his mind. Then, he opened his mouth and said: "In terms of density, to reach 17 grams per cubic centimeter, at room temperature, the tensile strength must reach 800 megapas.
There is nine percent elongation, and one of them is the sensitivity of adiabatic shear, the higher the better.”
When Mr. Huang asked Qin Zhenhua to provide performance data, he had a smile on his face and a confident heart. He could satisfy the data he proposed. At that time, he would admire him.
How could I know that Qin Zhenhua’s requirements were too high. None of their existing materials could meet this requirement. Moreover, there were probably not internationally, right?
You kid, is this trying to force others to do something, this kid is not real at all.
"How is this possible?" Sure enough, before Qin Zhenhua spoke, a young man came out of it. It seemed that he should be the student Huang as a tutor and was being taught here.
He came out with a test report. The tungsten alloy rod that had just been sintered had been placed on the testing machine next to it for testing.
Now, he came out to report and happened to hear Qin Zhenhua's request, and immediately refuted it.
"If you want to reach such a high density, you have to make the metal particularly dense, and the gaps between the metals are quite sparse, and in this way, the elongation cannot be achieved. Is it necessary to have that thermal shear?
Why do you want to pursue this belief?”
When Cheng Wang finished saying this, he felt a little regretful. The person in front of him was clearly here to make trouble. He proposed such high-level indicators and gave everyone a warning. Why should he have the same knowledge as such a person?
He actually told the difficulties.
The gap between this metal is of course the gap between metal atoms. Only by making the gap between atoms particularly small, the metal atoms and atoms closely arranged, and by pulling them between molecular forces, can we make the gap between them?
The density reaches such a high level.
In practice, it is impossible to do it now, let alone other performances.
"Yes, this is very difficult to achieve. If you want to meet the technical standards I mentioned, you can only use nanometers." Qin Zhenhua said.
"Nanometers, nanometers, what are nanometers?" Cheng Wang asked.
"Puff!" Qin Zhenhua finally couldn't help but spit out, brother, you can't even know what nanometer is, right?
Later, Cheng Wang also reacted: "I thought you were talking about an additive, it turned out to be a scale? Are you kidding, how can our processing accuracy reach nanometers?"
As the most proud disciple of Mr. Huang, Cheng Wang certainly couldn't not know what nanometers are. He just thought about it. To develop alloys with different properties, different trace elements are needed to add to it. The nanometer he just thought about was, thinking that
It is a trace element, and now I know that Qin Zhenhua is talking about a mark of scale.
Meters, centimeters, microns, nanometers, these are all related to the minus nucleus power of ten. When it reaches the nano level, it is the minus 9th power of ten, which is 0.0000000001 meters.
Now, their powder metallurgy technology is just processing the powder to the micron level, which is quite difficult. It is usually fine particles around a few hundred microns.
How is this possible to grind this powder to the nano-level? That level is already the size level of the atom!
The finer the metal powder, the more fully the metal will be mixed with other William elements during sintering, and the stronger the internal structure will be. However, if you want to say that you can grind to this level, you can think of it.
I dare not think about it.
Even Mr. Huang opened his eyes wide and looked at Qin Zhenhua.
"Yes, our processing accuracy is definitely not nanometers, but our research accuracy can reach the nanometer level. We can study how the atoms in the products formed by sintering, so that we can continue to carry out continuous
To improve and improve our process, abroad, scanning tunneling microscopes have just appeared this year, which can study the molecular and atomic levels. I think this technology is very important to our powder metallurgy industry.”
Researching to the nano level and how atoms combine together is the ultimate level for powder metallurgy!
If you can achieve this level, you will definitely get what you want.
