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

"Boss, can you not be so hasty next time!"

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

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

It's just that Zhang Xingyang is not very familiar with them, so it will take a long time to get used to it.

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

Su Xiao has been working under Zhang Xingyang for ten years and has become very mature in all aspects.

"Time waits for us not. 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 will age quickly if they lack sleep."

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

As a woman, especially a woman over thirty years old, it is difficult not to have appearance anxiety.

Even scholars who have won many honors are no exception.

Zhang Xingyang felt a little embarrassed, "After this period of busy work is over, I will give you a longer vacation."

"The development of new materials is actually going quite smoothly. Following the experimental ideas you gave me, I took someone to try it."

After getting the vacation she wanted, Lidya Su didn't complain too much and just gave it up.

"It has indeed successfully produced qualified 690 alloy."

Alloy 690 is a nickel-based alloy.

Mainly contains 27.0-31.0% chromium and about 59% nickel.

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

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

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

“But it’s still some way off from what we want.”

Lidya Su then told a piece of bad news.

However, Zhang Xingyang had already been mentally prepared for this and was not surprised at all.

690 alloy is more just for everyone to practice.

By the way, break the foreign blockade.

Prior to this, most alloy 690 was purchased from abroad.

It is also a "neck-stuck" technology.

"Can you complete the molding production of 690 alloy now?"

Zhang Xingyang is concerned about another issue.

In fact, it does not mean that 690 alloy cannot be produced in China. Small batch production is still possible.

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

Materials are not finished once they are produced.

Also need to be able to process.

Even if the primitive people were given a large piece of fine steel, it would be in vain if they could not complete the subsequent smelting and manufacturing.

As for 690 alloy, as an ultra-high temperature alloy, it 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 to shape it.

Zhang Xingyang said, "That's not bad. It can be regarded as filling a gap in the domestic materials field."

"Maybe I can win a prize or something."

The various awards 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 numerous to count.

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

So neither of them attaches great importance to these honors.

Honors are just some embellishments on their life path.

Su Xiao waved her hand, "Rather than winning the prize, I still want to have a good sleep."

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

When I was young, I might be able to work like this for a month.

But when one passes thirty, physical skills decline significantly.

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

"Don't worry, I will definitely let you rest for a day before starting the next round of experiments."

Zhang Xingyang didn't want anyone to be physically exhausted because of work.

Unnecessary overtime work is actually not encouraged in any team led by Zhang Xingyang.

"What we have to do next is actually the pipeline materials that are actually going to be used on 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 confusion.

Zirconium alloy is a relatively special alloy.

The time it was developed by humans was actually very short.

It has only been a hundred years.

The time for large-scale application did not even exceed thirty years.

But it has extremely excellent performance.

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

In other words, this thing is like the mithril, the universal metal in Western fantasy stories.

Lidya Su 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 little doubt about the real research content of the institute.

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

Later, the 690 alloy Zhang Xingyang asked him to develop was not considered a material that must be used in nuclear reactors.

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

But after seeing zirconium alloy, these doubts were dispelled.

Zirconium alloys are basically only used in nuclear reactors.

Rarely seen elsewhere.

Zirconium is not Chinese cabbage, it is very 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 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 wrote everything on it."

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

Different combinations can produce alloys for different uses.

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

Add appropriate amounts of iron, chromium, nickel, and solid solution limit niobium to the alloy.

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

Su Xiao looked at the various data on the paper carefully and said with a sigh:

"This is really a big deal. How much does it cost to have so many materials!"

Not counting the loss of various equipment used in the experiment, it is just the raw materials.

This experiment will cost tens of millions of yuan.

And it may not be successful.

"Let the people in your laboratory take a break first."

Zhang Xingyang said, "Start the experiment tomorrow."

Su Xiao waved the paper in her hand, yawned and said, "I know, I'll notify them later."

Lidya Su turned around and prepared to go back.

"Wait a moment."

Lidya Su turned around, blinking and wondering.

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

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

Only Su Xiao had been single before this.

For this reason, many young boys chased her before the institute.

But he was always rejected by Lidya Su.

Many people also know that Lidya Su has always been unrequitedly in love with the dean.

But Zhang Xingyang has never had any thoughts about love.

There is not even an ambiguous object.

Everyone thought it would continue like this.

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

Everyone wants to see if this is true.

It is understandable that even Zhang Xingyang, who never pays attention to these things, is a little curious.

Lidya Su'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 here, we would be getting married next month."

Zhang Xingyang was a little surprised. He didn't expect that Lidya Su's relationship would progress so quickly, to the point of discussing marriage.

"If this is the case, then our research and development progress will be faster, so as not to delay your life-long event."

The fake smile on Lidya Su's face was almost unsustainable, so she didn't say much.

He opened the office door directly, turned around and left.

The change in Su Xiao's face naturally did not escape Zhang Xingyang's eyes.

It was only for a moment, but it was 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 relationships, Zhang Xingyang is far from as good as others.

If we say that Zhang Xingyang is a rare talent in a thousand years in terms of scientific research.

So in terms of emotions, he is not as good as ordinary people.

If it were another person, it would be easy to find out in the scene just now that Su Xiao was lying.

Only Zhang Xingyang would think what she said was true.

And she really wants to complete the task within this period of time so that Lidya Su can get married smoothly.

"Sister Su, what's wrong?"

The researchers who entered the laboratory the next day quickly discovered something unusual about Su Xiao.

The two eyes are as red as light bulbs.

"It's nothing, the wind and sand in the institute are too strong, so I can't adapt to it." Su Xiao replied without stopping the movements of his hands.

Lidya Su’s answer is not wrong either.

The institute is located in the desert.

Every day when the wind blows, there is a sandstorm.

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

Each person can sweep two pounds of sand from their body every day.

But soon a more careful researcher discovered that Su Xiao's eyes were not red just because of the sandstorm.

"When I went back yesterday afternoon, I saw Sister Su. Her face looked ugly at that time."

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

"Did Sister Su get approved by the director?"

"Impossible, the director is not that kind of person."

"He is quite nice."

Several not very old researchers gathered together to secretly gossip about what happened to Su Xiao.

Just when they were getting close to the truth.

Su Xiao approached them expressionlessly, "Have you finished all your work? Are you here to chat?"

Lidya Su is usually nice to everyone.

So after seeing her coming, everyone started working like a good baby.

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

The vacuum consumable arc melting 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 materials laboratories.

But there are some problems with raw materials.

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

Vacuum arc melting requires higher purity.

Otherwise, it will be difficult to obtain a zirconium alloy with uniform composition and suitable proportions.

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

The experimenter wearing glasses said, "It will take at least two days to complete."

Small-scale refining in the laboratory is not impossible.

In fact, their equipment and technology are the most advanced in the country.

But time, they don't have that much.

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

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

“The issue of purity cannot be taken carelessly and rash smelting will result in more losses than gains.”

After finishing speaking, Su Xiao walked to another group of team members.

"How do you remember the vacuum arc melting technique?"

Adding materials during the smelting process requires operating a robotic arm.

Their work is relatively simple, just add materials according to time nodes.

Belonging is a job that requires patience and care.

However, there may not be time for them to read the operation manual at that time, so they can only remember it all in their minds.

"I almost remember it." The team member nodded.

The added material is actually not that much.

The operation is not complicated either.

It's not difficult to remember.

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

Then he returned to his office.

Lidya Su just left.

The spirit of Bagua, which had been suppressed, began to burn brightly in the laboratory again.

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

"You're going to die!"

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.

They fall in love with each other as soon as they go back and forth.

Apart from romance, gossip is the only thing in the institute that can appease everyone's boring hearts.

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

A researcher who was familiar with Su Xiao said after thinking about it based on the information he had just obtained.

"How to say?"

"Any gossip?"

Someone who didn't know much asked quickly.

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

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

"Then what?"

"Are they together?"

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

In particular, the director seems to have never been close to women.

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

"But recently it is said that Sister Su is in love."

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

Although Zhang Xingyang is usually friendly, he doesn't put on much airs.

But his identity and achievements still make people feel alienated.

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

Although it is bright and clear, it is still too far away from everyone.

"Probably not. Didn't someone see Sister Su coming out of the director's office with a bad look on her face yesterday?"

"Maybe they just had a quarrel?"

In the laboratory, two groups of people were instantly divided.

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

And the non-Xiaoxing faction who think they are not together.

Only the brother responsible for the refining work is still working silently. (End of chapter)
