Chapter 79 Single Crystal Copper (for further reading, recommended)

Chapter 79: Single Crystal Copper

"Your hand is really steady." Wang Xu straightened his body, holding a roll of newly made copper wire in his hand, which was golden and brilliant.

"It's not bad, it's not bad. It's a small practice, not bragging. If I take a grade test, I should at least be a fitter four." Wang Xu still didn't dare to blow hard, and a grade four is enough.

The eighth level is a bit exaggerated. Wang Xu has never learned the skills of a fitter systematically. He only knows how to do carpentry. Have you ever seen a worker in that kind of article?

However, the core of a fitter is the control and perception of various hands, so for Wang Xu, many carpentry skills can be translated.It's nothing more than the difference in processing materials. With a little practice, you can get started quickly, just like his jade carving skills.

"Did you come up with this method yourself? Have you ever studied metallurgy?" Professor Bian was very curious. This method is actually scientifically justified. After working in metallurgy for so long, Professor Bian certainly understands some basic principles.

"Yeah, it's just a bit of an inexplicable idea, so I want to try it out."

"Where did you learn metallurgy?"

"It's a family background. My dad is an engineer at Shougang. There are many books at home. When I was a child, I read a lot of novels." Wang Xu shrugged. .

The name of that book is "How Steel Is Tempered". Really, it's a popular science book on steel smelting that imitated the name of the novel.

But the predecessor is not stupid. After reading a few pages, I know that I have been fooled, but it is still no problem to tell a story.

"That's really a family background. Who is your father? Maybe I still know him. We have cooperated a lot with Shougang."

"My father's name is Wang Shude, the chief engineer of Shougang's hot-rolling laboratory," Wang Xu replied, and he was still very proud of his father.

"You are Lao Wang's son. I didn't expect you to be so old. Back then, I worked with your dad. Last year, I met your dad in, uh, a place I can't say.

I said how can you be so troublesome, if it is Lao Wang's child, it will be fine.At that time, he was active in thinking and able to toss a lot.

Speaking of which, I saw you when you were a child.

By the way, how is he doing now? Did he go back? "Professor Bian became more enthusiastic, it seems that he really knows Wang Xu.

"No, I came back for two months during the Chinese New Year, and then left again. It's been several months, and there is no news at all." Wang Xu pouted, his father was like this.

It's usually fine. Although it's a long way to go to work, I can still go home a few times a week, but I'm taken away by an expert from time to time, so I really don't have a trace.

Although his father never said what he did or where he went, Wang Xu was not stupid. Moreover, Wang Xu didn't think there was anything to keep his father's job secret.

Generally, the final product needs to be kept secret, not the steel used.

Of course, the metallurgical method of the specific steel is also kept secret, but there is no need to go to the valley to do it.

After all, the materials are quite basic, and in the end, they have to go back to Shougang to make them. Many equipments are not available everywhere.

Wang Xu didn't know what he wanted his father, an expert in iron and steel metallurgy, to do. Last time I heard that there was a problem with the preparation of the car frame. What car?

Can't say, I guess I'll see it in a few years.Wang Xu didn't bother to guess what it was, but anything that could keep his father busy for half a year would probably be seen in the square.

"Well, it's normal. Your father is very good, especially in heat treatment, which is top-notch." Professor Bian obviously admires his father a little, which makes Wang Xu feel a little proud.

"Thank you, but I feel that you are more talented than your father. Why, transfer to the material department, and I will let you blog directly in the future."

"No, no, the material is too difficult, IQ is not enough, I'd better learn automation." Wang Xu knew that Professor Bian knew his father, so it was easy to say.

And pulling himself like this was just a joke, so Wang Xu also made a joke.

"You boy, you really are a family, a bit like your father," Professor Bian laughed.

"Well, he likes to joke."

"No kidding, what are you planning to do with these copper wires? Are you making wires? Are you considering mass production?" Professor Bian brought the topic back and started discussing the newly produced copper wires again.

"Get some enameled wires. I haven't thought about what to do specifically. I can't make shielded wires yet. Let's talk about when this kind of thing is mass-produced. I'll get some back and see if I can improve the headphones. I am very interested in audio equipment. The demands are high."

"Okay, it's fine if you like it, toss and toss as much as you can, and if you need help with material science, just come to me.

I asked Xiao Cao to test this wire. If it is as I thought, then I am afraid you have created something amazing.

I've never seen a student who can struggle like you. "Professor Bian was a little emotional, but also looking forward to it.

"Thank you, what's your idea, what's your guess?" Wang Xu became curious, and he was also a little curious, since he got this technology.

This shouldn't be a simple purification process, but given his meager material science accumulation, he has never been able to figure out what it is.

"The foundation is still a bit weak. I feel that it may be single crystal copper. The next few operations you performed are likely to form single crystal, but this is just a guess." Professor Bian still spoke rigorously, which is the habit of old engineering students.

"Single crystal copper, okay, I'll go to study later." Wang Xu was a little bit at a loss. This thing is too professional, and it really can't be seen in daily life.

"The application of single crystal copper is still in a very early stage. If your thing is really single crystal copper, if it can be mass-produced, then I am afraid it will be the world's leader, at least it is also the world's advanced level."

"So good?" Wang Xu was surprised, half pretending.

"Indeed, at least the resistivity is consistent with that of single-crystal copper, and others need to be tested. I heard that you have applied for a patent. What are your plans for this technology?",
"If this thing is world-leading according to what you said, it is really difficult to apply for a patent. Applying for it means that the technology has been leaked. Do you know how to deal with this technology? I don't know if it can be transferred.

Please help to see if it can be transferred out. It is useless to have technology alone. It is meaningful to have funds for mass production. "Wang Xu expressed his position immediately.

"Look at the various indicators first, there are too many manual parts of your operation, you can't do this.

Need to consider the design of special equipment, don't worry.

Now that the parameters are out, let’s verify the results first, and hold a technical achievement evaluation meeting.

With the recognition of achievements, even if you do not apply for a patent, it can be transferred.

So, don’t worry, it’s better to use X-ray diffraction test for the certification of single crystal. It’s more rigorous. I asked Xiao Cao to do the simple ones first. X-ray diffraction is slower. It seems that the laboratory needs to make an appointment. up. "

(Popular science: There are four ways to confirm single crystal copper, X-ray diffraction, observation of diffraction patterns, high-power microscope observation, observation of crystal phase, compression test, and resistivity test, both of which are based on the consistency of each direction)
