Su Xiao's hair was a little messy, as if he had just experienced a strenuous exercise.

"Boss, can you not rush so much next time!"

Su Xiao yawned as she spoke, looking like she hadn't slept for several days.

There are actually quite a few big guys in the materials lab.

It's just that Zhang Xingyang and they are not very familiar with each other, and it takes a long run-in time to cooperate.

So he simply transferred Su Xiao from the Rocket Research Institute temporarily.

Su Xiao has been working under Zhang Xingyang for ten years, and he is already very mature in all aspects.

"Time is running out, we don't have that much time to wait."

Zhang Xingyang looked at her and said.

"I know, but you should also know that women age quickly without sleep."

Su Xiao touched his face and said, feeling that there were a lot of crow's feet in the corners of his eyes.

As a woman, especially one over thirty, it's hard not to have appearance anxiety.

Even academics who have received many honors are no exception.

Zhang Xingyang felt a little embarrassed, "After this period of time is over, I will give you a relatively long vacation." ”

"The development of new materials is actually quite smooth, according to the experimental ideas you gave, I took someone to try it."

got the vacation he wanted, Su Xiao didn't complain too much, and accepted it when he saw it.

"It is indeed a successful production of qualified alloy 690."

Alloy 690 is a nickel-based alloy.

It mainly contains 27.0-31.0% chromium and about 59% nickel.

It has excellent resistance to intergranular corrosion and intergranular stress corrosion cracking.

It is the heat exchange tube material used in the mainstream pressurized water reactor steam generator.

The Daya Bay Nuclear Power Plant and Qinshan Nuclear Power Plant, which were built before this, all used 690 alloy.

"But it's still a long way from what we require."

Su Xiao then told the bad news.

However, Zhang Xingyang has long been mentally prepared for this, and he is not surprised at all.

690 alloy, more just for everyone to practice their hands.

By the way, break the blockade abroad.

Prior to this, most of the 690 alloys were purchased from abroad.

It is also a "stuck neck" technology.

"Can you now complete the molding of Alloy 690?"

Zhang Xingyang is concerned about another issue.

In fact, it is not that 690 alloy cannot be produced in China, and small batch production is still possible.

It's just that the processing technology is not very good.

Materials are not just produced and finished.

It also needs to be able to process.

Even if they gave the primitive people a large piece of steel, they couldn't complete the subsequent smelting and manufacturing, it would be in vain.

The 690 alloy, as an ultra-high temperature alloy, is still very difficult to process.

Su Xiao nodded, "Our previous laser integrated molding technology can directly process 690 alloy. ”

Prior to this, the Rocket Research Institute actually mastered the processing technology of high-temperature superalloys.

Metal powder is processed by laser and molded.

Zhang Xingyang said, "That's okay, it can be regarded as filling a gap in the domestic material field." ”

"Maybe, I'll get a prize or something."

The various awards that the institute has received over the years can even fill three rooms.

There are more than a dozen national-level honors alone.

Zhang Xingyang's personal awards are too many to count.

Su Xiao has won fewer awards, but there are dozens.

So neither of them values these honors very much.

Honor is just some embellishment on their life path.

Su Xiao waved his hand, "Compared to winning the award, I still want to get a good night's sleep." ”

"I've been sleeping less than four hours a day these days."

When you are young, you may be able to work like this for a month.

But when people are over 30, their physical skills decline significantly.

In less than a week, I couldn't hold on.

"Don't worry, you'll definitely be given a day off before the next round of experiments begins."

Zhang Xingyang didn't want people to collapse their bodies because of work.

Unnecessary overtime is actually not advocated in the various teams led by Zhang Xingyang.

"What we need to do next is actually the pipe material that is really going to be applied to the molten salt pile."

Zhang Xingyang took out a handwritten document.

"N36 zirconium alloy?" Su Xiao looked at the handwritten document and said with some doubts.

Zirconium alloy is a special type of alloy.

The time it has been exploited by humans is, in fact, very short.

It's only been a hundred years.

The time for large-scale application is not even more than 30 years.

But it has excellent performance.

In metal smelting, adding a little zirconium can improve mechanical properties and corrosion resistance.

In other words, this thing is like Mithril in the Western Fantasy story, the universal metal.

Su Xiao was only slightly surprised, and then calmed down, "Sure enough, what you said before is true." ”

After Su Xiao came to the Nuclear Research Institute, he actually had a trace of doubts about the real research content of the Institute.

Because she couldn't believe that she could still deal with nuclear weapons in her life.

The 690 alloy that Zhang Xingyang asked him to develop was not considered a material that had to be used in nuclear reactors.

This made Su Xiao always have doubts about the research content of the institute.

But after seeing the zirconium alloy, these doubts were dispelled.

Zirconium alloys are basically only used in nuclear reactors.

It's rarely seen anywhere else.

Zirconium is not bok choy, it is expensive.

Moreover, zirconium has a very low thermal neutron absorption cross-section and performs well in a nuclear radiation environment.

"I plan to try the vacuum self-consumable arc melting method first, as for the proportion of alloying elements and materials, as well as the smelting sequence."

Zhang Xingyang pointed to the paper in Su Xiao's hand, "I've written it all on it." ”

There are many kinds of material matching ratios of zirconium alloys.

Different collocations can obtain alloys for different purposes.

What Zhang Xingyang gave is basically a zirconium and niobium formula.

Add an appropriate amount of iron, chromium, nickel, and niobium to the solution limit in the alloy.

This alloy has the best corrosion resistance, which can reach more than 22 times that of the previously mentioned 690 alloy.

Su Xiao looked at the data on the paper carefully, and said with some smack:

"That's a lot of money, how much does it cost to have so many materials!"

Not counting the loss of equipment used in the experiment, only raw materials.

This experiment will cost tens of millions of yuan.

And it doesn't always work out.

"Let's give the people in your lab a break."

Zhang Xingyang said, "I'll start the experiment tomorrow." ”

Su Xiao waved the paper in his hand, yawned and said, "Got it, I'll go and inform them later." ”

Turning around, Su Xiao was ready to go back.

"Wait a minute."

Su Xiao turned around, blinking his eyes for some reason.

Zhang Xingyang said with some gossip: "I heard that you have a boyfriend, is it true?" ”

In the research institute, among the peers who are about the same age as Zhang Xingyang.

Only Su Xiao was still single before this.

For this reason, there were many little boys who chased her before the research institute.

It's just that Su Xiao has always refused.

Many people also know that Su Xiao has always been unrequited in love with the dean.

But Zhang Xingyang has never had the idea of love.

Not even an ambiguous object.

Everyone thought it would go on like this.

But recently, it is said that Su Xiao has a boyfriend younger than her.

Everybody wants to see if it's true.

Even Zhang Xingyang, who has never paid attention to these, is a little curious, so you can imagine it.

Su Xiao's face turned pale, and then returned to normal, "Yes, we have a good relationship and are preparing to get married." ”

"If you hadn't transferred me, we'd be getting married next month."

Zhang Xingyang was a little surprised, he didn't expect Su Xiao's relationship to progress so quickly, to the point of talking about marriage.

"In this case, then our R&D progress should be faster, and it is not good to delay your lifelong event."

The smirk on Su Xiao's face was almost unbearable, so he didn't say much.

Pushed open the office door and turned to leave.

Su Xiao's face changed, and naturally he did not escape Zhang Xingyang's eyes.

It's only for a moment, but it's still obvious.

"Is there something special about her boyfriend?"

Zhang Xingyang thought in his mind while sorting out the work at hand.

In terms of feelings, Zhang Xingyang is far from being as good as others.

If it is said that Zhang Xingyang is a rare talent in scientific research.

Then in terms of feelings, he is not as good as ordinary people.

Changing to another person, it was easy to find out in the scene just now that Su Xiao was lying.

Only Zhang Xingyang will think that what she said is true.

And he really wants to complete the task during this time, so that Su Xiao can get married smoothly.

——

"Sister Su, what's wrong?"

The researcher who entered the laboratory the next day quickly discovered Su Xiao's abnormality.

The two eyes were as red as light bulbs.

"It's nothing, the wind and sand in the institute are too big, so I don't adapt to it." Su Xiao replied without stopping the movement of his hand.

Su Xiao's answer was not faulty.

The institute is located in the middle of the desert.

Every day, as long as the wind blows, it is a sandstorm.

Especially in recent times, it has been windy almost every day.

Each person is able to sweep two pounds of sand out of their body every day.

But soon, more attentive researchers found that Su Xiao's eyes didn't seem to be red simply because of the wind and sand.

"When I went back yesterday afternoon, I saw Sister Su, and her face was ugly at that time."

"I saw it too, when she just came out of the director's office."

"Was Sister Su criticized by the director?"

"No way, the director is not like that."

"He's very nice."

A few researchers, who were not very old, gathered together to secretly gossip about what happened to Su Xiao.

Just when they were about to get closer to the truth.

Su Xiao approached them expressionlessly, "Are you all done with your work?" Here's a small talk? ”

Su Xiao treats everyone well on weekdays.

So after seeing her coming, everyone started their work as if they were good babies.

The development of zirconium alloy is much more difficult than Su Xiao thought before.

The vacuum self-consumable arc smelting proposed by Zhang Xingyang alone is not a simple matter.

In terms of equipment, vacuum chambers and electric arc furnaces are mainly used.

These processing environments and equipment are still available in the materials laboratory.

But in terms of raw materials, there are some problems.

The zirconium raw materials they currently have are not pure enough!

Vacuum arc melting, which requires a high degree of purity.

Otherwise, it is difficult to obtain a zirconium alloy with uniform composition and suitable proportion.

"Sister Su, our raw materials still need to be refined before they can be used."

The bespectacled experimenter, "It will take at least two days to complete." ”

Small-scale refining in the laboratory is not impossible.

In fact, they are the most advanced in the country in terms of equipment and technology.

But time, they are not so much.

Two days is enough for them to do a lot of things.

"You do the refining first." Su Xiao frowned.

"The purity problem must not be sloppy, and rashly smelting will outweigh the losses"

After finishing speaking, Su Xiao walked over to the other group of members.

"How do you remember the method of vacuum arc melting?"

In the smelting process, the addition of materials is carried out by operating a robotic arm.

Their work is relatively simple, and they can be fed according to the time node.

Belonging is a job that requires patience and care.

However, there may not be time for them to read the manual, so they can only memorize it all in their heads.

"I remember almost." The group members nodded.

The added material, in fact, is not very much.

The operation is also not complicated.

It's not a hard thing to remember.

Su Xiao walked around the laboratory, focusing on the refining and processing group.

Then he returned to his office.

Su Xiao had just left.

The soul of gossip, which had been suppressed, began to burn in the laboratory again.

"Sister Su's face is so ugly today, exactly the same as when Xiaohan came to her aunt."

"Death to you!"

The female researcher next to the boy couldn't help but punch him directly.

Life at the nuclear research institute is a bit boring, and everyone is young.

Come and go and fall in love with each other.

In addition to talking about love, only gossip can soothe everyone's boring heart.

"I think Sister Su may have some emotional problems."

There is a researcher who is more familiar with Su Xiao, and said after thinking about the information he just got.

"How?"

"Any gossip?"

People who are not too clear hurriedly asked.

"According to some old people, Sister Su liked our director for many years before this."

"At that time, Sister Su had just left the campus, and she met the director, and then it was love at first sight."

"And then?"

"Are they together?"

The gossip involving the leader instantly aroused everyone's curiosity.

Especially the director doesn't seem to be close to women all the time.

"It is said that there is no, Sister Su has been single all these years."

"But recently, it is rumored that Sister Su is in love."

"I just don't know if the subject is the director?"

Although Zhang Xingyang is friendly on weekdays, he doesn't put on a show much.

But his identity, his achievements, still make people can't help but feel alienated.

For everyone, he is like the bright moon in the sky.

Although it is bright, it is too far away from everyone after all.

"Shouldn't it be, didn't someone see Sister Su coming out of the director's office with a bad face yesterday?"

"Maybe they just quarreled?"

In the laboratory, two groups of people were divided in an instant.

They are the Hyosung faction who think that Su Xiao and Zhang Xingyang are together.

and the non-Hyosung faction who thinks they are not together.

Only the elder brother who is in charge of refining is still working silently. (End of chapter)
