A big country of aerospace with black technology

"The sintering condition looks like it should be pretty good."

Su Xiao looked at the aluminum alloy materials being gradually completed in SPS and said.

Modern powder metallurgy seems to have many similarities with ancient fired ceramics.

They are all prepared by heating and sintering metal powder or other materials into a monolithic material.

However, the level of modern technology is not comparable to the ancient times when even temperature control could only be judged by flames.

The SPS technology used by Zhang Xingyang and others is a discharge plasma sintering system.

The discharge plasma is directly passed between the raw material powders for sintering.

Compared with traditional heating methods, the temperature of plasma is very high.

Plasma is a dissociated high-temperature conductive gas with a temperature of at least 4,000 degrees and a maximum of more than 10,000 degrees.

There are many ways to generate plasma, including heating, discharge, light excitation, etc.

The SPS device used by Zhang Xingyang and others uses DC discharge.

The material sinteres very quickly, and the heating time is only 32 minutes.

Operate the device and keep warm for 7 minutes.

The material enters a cooling period of up to 30 minutes.

"The sintering condition of the material should be pretty good."

Su Xiao said after looking at the equipment.

"We won't know the specific situation until the burning is completed." Zhang Xingyang said calmly.

Although the failure rate of SPS sintering is very low, this is the first time this material formula has been subjected to sintering experiments.

Zhang Xingyang would not be particularly surprised if any strange situation happened.

For materials sintered by high-temperature plasma, the cooling time is almost the same as the heating time.

There is nothing that can be done about it, after all, the temperature is too high.

Half an hour later, everyone in the laboratory was surrounding the newly burned material.

I rush to test the performance of the material first.

The materials laboratory has been undergoing various expansions over the years. After all, the research work is almost never finished.

So even within this high-temperature plasma laboratory, there are many young researchers who have just graduated two or three years ago.

These young researchers have also heard from a few old people in the laboratory that their dean has a hopeless attainment in materials science.

Even a material formula that was taken out at random saved a company that was on the verge of bankruptcy.

These are basically researchers who graduated from top domestic universities, and now many of them are working in Longteng Materials Group after the expansion of 703 Factory.

It is also the first time they know that this leading domestic material company with billions of annual revenues still has such a history.

In the end, a handsome-looking boy got the chance to conduct the first round of testing on the material.

The materials were skillfully placed on the testing table, and various performance tests were carried out on the materials.

"this?"

"really?"

"This performance is a bit outrageous!"

The young researchers around were all surprised when they saw the data after the test.

It stands to reason that when they were in school, they basically participated in joint development projects with the Rocket Research Institute.

Since the specific investment in colleges and universities began a few years ago, many good seedlings have been cultivated for the research institute every year.

In these joint projects, they have also seen the real equipment and relatively top materials used in scientific research.

But compared with the small piece of material in front of them, those materials that once seemed extremely powerful are nothing.

"How is the performance? Let me see."

Seeing the completion of the material performance test, Zhang Xingyang also stopped to chat with Su Xiao beside him.

The two were discussing the experimental time for the next material formula.

Received the experiment report from the little boy next to the testing table.

After Zhang Xingyang looked carefully, he frowned and said:

"It's about eight percent lower than I expected."

The young researchers around him looked at each other after hearing this to confirm that they heard correctly.

They all sighed in their hearts, is this the world of the boss?

At this time, the word Versailles has not yet derived the meaning of inadvertently showing off, otherwise they would definitely say the last sentence: "Versailles!"

"But the current performance should be enough."

Zhang Xingyang didn't get too entangled in the performance of the material. This time, he made these in order to test whether the Yingjiang Materials Laboratory was falsifying the performance of the material.

By achieving this kind of performance, we can already test out a little bit of their stuff.

As long as they can still complete the upgrading of materials within a short period of time, it is almost certain.

There is definitely something wrong with the material performance test report they made before.

But Zhang Xingyang didn't just make such a formula. Compared with the current material, he took out twelve formulas in one go!

The reason why I didn't do it before is also very simple.

That is, these materials are of no use either to the Rocket Research Institute or to the country.

Naturally, Zhang Xingyang couldn't spend his time and energy on doing this.

Taking it out this time is just a matter of smooth sailing.

A month later, twelve articles signed by a certain materials laboratory appeared in materials journals.

"Now, it depends on whether you follow or not."

Zhang Xingyang held the magazine open in his hand, looked at the material on it that almost completely disclosed the preparation route, and said with a smile.

At the same time, it was still late at night on the other side of the ocean.

But as a scientific research unit, working overtime all night is almost commonplace.

This is the same no matter which country you are in.

"Pryce, I think you should take a look at this journal."

A researcher in the institute held a magazine with a serious face and said to Prius, who was still immersed in his work.

"What's wrong, Ryan?"

Preuss asked with some confusion while taking the journal handed over by the other party.

"Read this article first."

Ryan did not directly answer Preuss's question, but pointed to an article in the journal and said.

After Prius lowered his head and glanced for a few times, he raised his head and said:

"Which research institute came up with this deceptive data?"

"Obviously fake!"

Who knew that Ryan's face was very heavy:

"I thought so at first."

"But I thought their preparation method was very interesting, so I asked my people to experiment."

"As a result, the discrepancy between the performance data and the journal is about one percent."

When saying this, Ryan's expression changed significantly, with a hint of disbelief.

"This is impossible!"

Even though his long-time friend Ryan said this, Preuss still found it difficult to accept it at first.

After a while, he emphasized:

"This is absolutely impossible!!!" (End of Chapter)
