"The sintering situation looks pretty good."

Su Xiao looked at the aluminum alloy material that was gradually completed in the SPS and said.

Modern powder metallurgy seems to have a lot of similarities with ancient fired ceramics.

All of them are prepared into a whole piece of material by heating and sintering, and metal powder or other materials are prepared.

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

Zhang Xingyang: The SPS technology they use, that is, the discharge plasma sintering system.

It is sintered by passing a discharge plasma directly between the raw materials and powders.

Compared to conventional 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 Celsius and a maximum of more than 10,000 degrees.

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

Zhang Xingyang: The SPS device they use is DC discharge.

The sintering of the material is very fast, and the heating time is completed in just 32 minutes.

After operating the device, it has been kept warm for 7 minutes.

The material goes into a cooling period of up to 30 minutes.

"The sintering of the material should be fine."

Su Xiao said after looking at the equipment.

"What the specific situation is, we will not know until it is burned." Zhang Xingyang said calmly.

Although the failure rate of SPS sintering is very low, this is the first time that this material formulation has been sintered experimentally.

If there is any strange situation, Zhang Xingyang will not feel particularly surprised.

The cooling time of the material sintered by high-temperature plasma is almost the same as the heating time.

There is no way around it, after all, the temperature is too high.

Half an hour later, everyone in the laboratory gathered around the materials that had just been burned.

I want to prioritize testing the performance of the material myself.

Over the years, the materials laboratory has been undergoing various expansions, after all, the research work is almost never finished.

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

These young researchers, who have heard from the few old people in the laboratory, have mentioned that their dean has hopeless attainments in materials science.

Even a casual ingredient recipe saved a business on the verge of collapse.

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

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

Eventually, a clear-eyed boy was given the opportunity to test the material for the first round.

The material is expertly placed on the test bench and tested for a variety of different properties.

"This?"

"Fake, right?"

"That's a bit outrageous!"

The young researchers around looked at the data after the test and were all surprised.

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

Since a few years ago, since the specific investment for universities began, we have been able to cultivate a lot of good seedlings for the institute every year.

In these joint projects, they can be regarded as seeing the equipment and top-notch materials that are really used in scientific research.

But compared to the small piece of material in front of them now, the materials that once seemed to be extremely powerful seemed to be nothing.

"How the performance is, I'll see."

Zhang Xingyang saw that the material performance test was completed, and he also stopped to chat with Su Xiao beside him.

The two are discussing the experimental time for the next material formulation.

He took the test report from the little boy next to the testing table.

After Zhang Xingyang looked at it carefully, he frowned and said:

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

The young researchers around them looked at each other after hearing this, and confirmed that they had heard correctly.

I all sighed in my heart, is this the world of the big guy?

It was at this time that the word Versailles had not yet been derived from the meaning of inadvertently showing off, otherwise they would surely have said: "Versailles!" ”

"But with the current performance, it should be enough."

Zhang Xingyang did not worry too much about the performance of the material, and this time he did this in itself to test whether the Eagle Sauce Material Laboratory was cheating on the performance of the material.

With this kind of performance, I have been able to test out a little bit of them.

As long as they are still able to complete the material replacement in a short period of time, then it is almost certain.

There was definitely something wrong with the material performance test report they had done before.

However, Zhang Xingyang didn't just make such a formula, the performance was much improved compared to the current material formula, he took out twelve at once!

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

That is, these materials are of little use either for the rocket research institute or for the state.

Zhang Xingyang naturally couldn't spend his mind and energy to do this.

Take it out this time, that is, push the boat down the river.

A month later, 12 articles signed by a materials laboratory appeared in materials journals.

"Now, it's up to you to follow or not."

Zhang Xingyang held the magazine in his hand, looked at the materials 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 true regardless of the country.

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

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

"What's wrong, Ryan?"

Priss asked with some puzzlement as he took the journal handed over by the other party.

"You look at this article first."

Lane didn't answer Price's question directly, but pointed to an article in the journal.

After glancing down a few times, Prius raised his head and said:

"Which institute came up with this deceptive data?"

"Obviously fake!"

Who knew that Ryan's face was very heavy:

"That's what I thought at first."

"But I thought the way they prepared it was interesting, so I let my men experiment with it."

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

As he said this, Ryan's face changed visibly, with a hint of disbelief.

"It can't be!"

Even if his long-time friend Ryan said this, it was still difficult for Prius to accept it at first.

After a while, he emphasized:

"It's absolutely impossible to !!" (End of chapter)
