Qin Zhenhua smiled.

Although it is the first time to come here, Qin Zhenhua has been tirelessly researching tanks and firepower in the past few years, in order to study advanced armor-piercing technology, of course, he has also studied how to improve the performance of tungsten alloy, but after he has read some information, he knows that he does not have this ability. This is the gap between experts and scholars and ordinary people.

He can understand the various introductions of popular science, but real research, that is the need to immerse in this profession for many years, all kinds of smelting technology, a small change, will bring a huge difference in product performance, which in addition to the need for professional skills, but also how many times of experiments, to be able to accurately find the best combination.

However, being able to see the other party's device at a glance also shows that Qin Zhenhua, a layman, actually has a very high professional level, which also attracted Huang Lao's attention.

"Our little friend's vision is not ordinary." Zhu Lao said: "Now, I am helping him work." ”

The research and development of the second-generation tank of the first machine factory actually has nothing to do with Zhu Lao, Zhu Lao was fooled by Qin Zhenhua in the past, so it is not wrong to say that he is helping Qin Zhenhua to do his work now.

Huang Lao's eyes became more keen, and he looked at Qin Zhenhua: "Oh? What a talent. So, it's a machine factory? ”

"That's right, I'm a worker in a machine factory." Qin Zhenhua said: "Huang Lao, we want to build the most advanced tank, and we need your technical support here. ”

"Hey, it's really an expert, I looked at it from the outside, and I knew it was a tungsten alloy rod, Lao Zhu, did you tell him?" Huang Lao asked with a smile.

"Of course not, the layman looks at the excitement, the insider looks at the doorway, our little friend, there are a lot of tungsten alloy in his hands, of course, you can see it at a glance." Zhu Lao said.

"Well, what kind of performance do you want?" Huang Lao didn't say what kind of tungsten alloy he was burning now, but asked Qin Zhenhua what he wanted.

"What we want..."In Qin Zhenhua's mind, countless data suddenly appeared, and 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 megapascals, and the elongation rate is nine percent. ”

When Huang Lao asked Qin Zhenhua to mention the performance data, he had a smile on his face and confidence in his heart, and he could be satisfied with the data he proposed, and when the time came, let him admire it.

Who knows that Qin Zhenhua's requirements are too high, and none of the materials they have can meet this requirement, and besides, internationally, I'm afraid there is none, right?

You kid, this is difficult in the strongman, this kid is not real at all.

"How is this possible?" Sure enough, before Qin Zhenhua could speak, a young man came out of it, looking like that, it should be Huang Lao, as a tutor, and the student brought here.

He came out with a test report, and the tungsten alloy rod that had just been sintered had been put on the testing machine next to it for testing.

Now, when he came out to report, he happened to hear Qin Zhenhua's request, and immediately refuted it.

"If you want to achieve that high density, you have to make the metal very dense, the voids between the metals are quite rare, and in this case, the elongation is not possible, is there any need for that adiabatic shear? Why pursue this belief? ”

When Cheng Wang said this, he regretted it a little, the person in front of him clearly came to find trouble, and put forward such a lofty indicator to give everyone a horse, why should he be familiar with this kind of person?

He actually told the difficulty.

The gap between the metals, of course, is the gap between the metal atoms, only by making the gap between the atoms particularly small, the metal atoms and the atoms are closely arranged, and the density can reach such a high degree by relying on the action between the molecular forces.

In practice, this is not possible at all, let alone other performances.

"Yes, this is very difficult to do, if you want to meet the technical standard I said, it is estimated that you can only use nanometers." Qin Zhenhua said.

"Nano, nano, what is nanometer?" Cheng Wang asked.

"Poof! Qin Zhenhua finally couldn't help it, and squirted out, brother, you can't even know what a nanometer is, right?

Later, Cheng Wang also reacted: "I thought you were talking about an additive, but it turned out to be a scale?" Are you kidding, how can the precision of our processing reach nanometers? ”

As the most proud disciple of Huang Lao, of course it is impossible for Cheng Wang not to know what a nanometer is, but he just thought about it, and to develop alloys with different properties, different trace elements need to be added to it.

meters, centimeters, micrometers, nanometers, these are all the negative cubic relations of ten, and at the nanometer level, that is the negative ninth power of ten, that is, 0.0000000001 meters.

Now, their powder metallurgy technology only processes the powder to the micron level, which is not easy, and it is generally about a few hundred microns of fine particles.

How is it possible to grind this powder to the nanometer level? At that level, it's already the size level of the atom!

The finer the powder of the metal, the more fully the metal will be mixed with other William elements during sintering, and the stronger the structure will be formed inside, but it is unthinkable to say that it can be ground to this level.

Even Huang Lao's eyes widened and he looked at Qin Zhenhua.

"Yes, our processing accuracy is absolutely not up to nanometers, but our research accuracy can reach the nanometer level, we can study how the atoms are combined in the sintering products, so as to continuously improve and enhance our process, in foreign countries, this year has just appeared scanning tunneling microscope, can be studied to the molecular and atomic level, I think, this technology, for our powder metallurgy industry, is quite important."

Studying to the nano level, to the level of how atoms are combined, for powder metallurgy, this is to reach an extreme!

If you can do this, you will definitely be able to get what you want.
