Chapter 752

Two high-temperature resistant materials, chromium alloy and graphite, are doped into molten steel.

The process has become much more complicated.

But fortunately.

After the experience of many failures, Gu Lu and Director Wen are obviously much more proficient in this operation process.

A few days later.

A standard-size steel-graphite-chrome plate is thus made.

As always, the steel plate was put into a high-temperature test chamber for testing.

Gu Lu and Director Wen stood nervously on the side, staring at the state of the steel plate in the high-temperature box with anxiety in their eyes.

Gu Lu and Director Wen both knew.

If this experiment fails.

That means that the direction they have chosen is completely wrong.

Everything that was before had to be pushed all over again.

It's not just a waste of time, effort, and money.

It will also deal a big blow to the self-confidence of the two.

Thereupon.

From the bottom of my heart.

Gu Lu and Director Wen are looking forward to the success of this experiment.

One minute, five minutes, ten minutes, fifteen minutes......

In the anxious mood of Gu Lu and Director Wen, time passed minute by minute.

Finally.

The long thirty-minute test period is over.

The steel-graphite-chrome alloy plate was still lying quietly in the high-temperature test chamber, and it looked the same as before.

However, Gu Lu and Director Wen did not take it lightly.

Once the steel-chrome alloy plate was that time.

After the experiment, the appearance of the experimental material did not change much, but when touched by external force, it directly turned into dust.

Carefully open the lab box.

Gu Lu held a pair of tweezers in his right hand.

Glancing at Director Wen, Gu Lu whispered, "Director Wen, I'm starting to clip it?"

Director Wen swallowed a mouthful of saliva, the sweat on his forehead revealing the nervousness and apprehension in his heart, "Clip it!"

Gu Lu nodded and put the tweezers into the high-temperature experiment box.

Gu Lu didn't start clamping directly, but first knocked on the steel-graphite-chromium alloy plate with tweezers.

Well, hard bang!

It didn't shatter at the first touch, and the tweezers made a crisp impact sound when they came into contact with the steel plate.

"There's a play!"

Gu Lu's face instantly became happy.

The result now is obviously much better than the last time the steel-chrome alloy plate was made.

Immediately, Gu Lu no longer hesitated, and directly clamped out the steel plate with tweezers.

on the bench.

Director Gu Lu and Director Wen used many advanced instruments to test the data of this steel-graphite-chrome alloy plate that lasted for half an hour at a temperature of 3,300 degrees.

In terms of quality, the steel-graphite-chromium alloy plate after high temperature is reduced by about five percent.

Most of these five percent are moisture and some surface impurities in this material.

In terms of volume, the change is very small, almost the same as before being put into the high-temperature experiment box.

As for the strength......

This value is quite variable.

Through the data after the test, it can be concluded that the strength of the steel-graphite-chromium alloy plate after the experiment is about 40% lower than that of the steel-graphite-chromium alloy plate before the experiment.

But......

What made Gu Lu and the others breathe a sigh of relief was that.

Because the original steel-graphite-chromium alloy has a very high strength, even if it is reduced by 40%, it can still face various complex vacuum environments in space.

In other words.

In terms of strength, the steel-graphite-chromium alloy composite materials designed and developed by Gu Lu and Director Wen are fully up to standard.

And in terms of the core high-temperature properties of this material, it can last for 30 minutes in an environment of 3,300 degrees Celsius, which can already say a lot.

As for the cost......

Gu Lu and Director Wen had almost estimated.

Because of the addition of graphite, the cost of this material is higher than the steel-chromium alloy material envisioned by Director Wen before.

But not too high.

It's about 10 million units.

This price, neither high nor low, should be considered within an acceptable range for the China Space Agency.

Such.

Extremely high strength, high temperature resistance and a low price tag – all three of these requirements are met by this new material.

So far.

It can be officially announced that the research and development of new materials by Gu Lu and Director Wen has been successful.

Next.

You only need to get this new material, and the slightly complicated production process is completely complete.

Holding the data report sheet in his hand, Director Wen's chubby face once again had a happy smile.

"Ha, Gu Lu, we finally succeeded!"

Director Wen was beaming with joy.

Although Gu Lu's project is not the most difficult R&D project that Director Wen has ever participated in, let alone the most time-consuming research project, it is definitely the one that he has failed the most.

Count them down.

He and Gu Lu had failed a total of three hundred and twenty times.

For ordinary scientific researchers, they may fail dozens of times and then give up.

But they failed ten times as often.

It's so hard!

It's so hard!

Director Wen didn't have the idea of giving up halfway through.

But when he thought that he had asked to join this project at the beginning, Gu Lu hadn't given up yet, so how embarrassed was he to quit halfway.

No matter what, he can't lose to a junior who is nearly twenty years younger than him.

So, Director Wen persevered all the way.

Moreover, throughout the research process, Director Wen continued to look at Gu Lu with admiration.

It's not three days, but every day passes, and Director Wen has to look at Gu Lu with a new eye.

There's no way, Gu Lu's learning ability and growth speed are really amazing.

At first, Director Wen thought that Gu Lu was about the same talent as him in the field of materials physics.

Later, Director Wen realized.

It's that he's overestimating himself.

Gu Lu's talent in the field of materials physics is obviously stronger than him.

Director Wen witnessed it with his own eyes.

From the beginning of Gu Lu's entry into the laboratory, many basic knowledge still needed to consult books, but now, he can flexibly apply many profound and obscure theories, and even boldly integrate material physics and mathematical theories, and achieve good results.

Thereupon.

Looking at Gu Lu, who was looking down and sorting out the data, Director Wen pushed his glasses, his eyes rolled, and he started to dig the foot of the wall.

"Gu Lu, when will you be able to finish the work at the rocket research and development base?" Director Wen pulled a chair, sat closer to Gu Lu, and then asked with a smile.

Gu Lu didn't know why Director Wen suddenly asked this question, but he still replied, "It's hard to say. ”
