Chinese entertainment for engineering students

Chapter 79: Single crystal copper

"Your hands are so steady." Wang Xu straightened his body and held a roll of newly made copper wire in his hand, which was golden and brilliant.

"It's not bad, it's not bad. I'm doing small training, not bragging. If I take the grade test, I'll be at least four in fitter." Wang Xu still didn't dare to brag too hard. Level four was enough.

Level eight is a bit exaggerated. Wang Xu has not systematically learned the skills of fitter. He only knows carpentry work. Have you ever seen workers in that kind of writing?

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

"Did you figure out this method yourself? Have you studied metallurgy?" Professor Bian was very curious. This method actually has scientific reason. Professor Bian has been engaged in metallurgy for so long, so of course he understands some basic principles.

"Yeah, I just have a weird idea and I want to try it out."

"Where did you learn metallurgy?"

"It comes from my family. My dad is an engineer at Shougang. There are a lot of books at home. I read a lot of them as novels when I was a kid." Wang Xu shrugged. This is true. His dad once lied to his predecessor and asked him to read them as novels. .

The name of that book is "How Steel Was Tempered". It's really a book that imitates the title of a novel and is a popular science book about steel smelting.

However, the predecessor is not stupid, and after reading a few pages, you will know that you have been fooled, but it is still no problem when it comes to telling a story.

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

"My father's name is Wang Shude, the chief engineer of Shougang Hot Rolling Laboratory," Wang Xu replied. He was still very proud of his father.

"You are Lao Wang's son. I didn't expect you to be so old. I worked with your dad back then. Last year, I met your dad in, well, somewhere I can't tell you.

I said, how can you be so tossing, if it were Lao Wang's child, it would be no problem. At that time, he had an active mind and was very capable of doing things.

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

By the way, how is he now and has he gone back? "Professor Bian became more enthusiastic. It seemed that he really knew 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's no news at all." Wang Xu curled his lips, his father was like this.

Normally, I'm fine. Although I have to go to work quite far away, I can still go back home a few times every week. But from time to time, I'm dragged away by being an expert, and then I'm really gone.

Although his father never said what he was doing or where he was, Wang Xu was not stupid, and Wang Xu didn't think there was anything confidential about his father's work.

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

Of course, the specific metallurgical method of the steel itself is also confidential, but there is no need to go to the mountains and valleys to do it.

After all, materials are quite basic. In the end, you have to go back to Shougang to manufacture them, and a lot of equipment is not available everywhere.

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

I can’t say, I’ll probably 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 dad is very good, especially in heat treatment. He is top-notch." Professor Bian obviously admired his dad very much, which made Wang Xu feel a little proud. This is the sequelae of the damn combination.

"Thank you, but I feel like you are more talented than your dad. How about I switch to the Materials Department and I'll let you do the master's degree in the future."

"No, no, the material is too difficult and I don't have enough IQ. I'd better learn automation." Wang Xu found out that Professor Bian knew his father, so it would be easier to say.

And it was just a joke to tease him like this, so Wang Xu also made a joke.

"Boy, you are really 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? Make conductors? Are you considering mass production?" Professor Bian brought the topic back and started discussing the newly produced copper wires again.

"Get some enameled wire. I haven't thought about what to do specifically. I can't make shielded wire yet. I'll wait until when this kind of thing is mass-produced. I'll get some back and see if I can improve the headphones. I'm interested in the audio equipment. The requirements are very high.”

"Okay, if you like it, just toss and toss as much as you can. If you need help with materials science, just come to me.

I asked Xiao Cao to test this wire. If it’s as good as I thought, then I’m afraid you’ve made something great.

I've never seen a student as flexible as you. "Professor Bian was a little emotional, but also a little expectant.

"Thank you. What are your thoughts and your guesses?" Wang Xu was curious. He was actually a little curious. He had felt this way since he got this technology.

This should not be a simple purification process, but given his meager accumulation of materials science, he has never been able to figure out what it is.

"The foundation is still a bit weak. I feel it may be single crystal copper. Your subsequent operations may very well form a 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 study later." Wang Xu was a little confused. This thing is too professional and cannot be seen in daily life.

"The application of single crystal copper is still at a very early stage. If your product is really single crystal copper, and if it can be mass-produced, then it will probably be the world leader, or at least 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. Others still 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 as you said, it would be really difficult to apply for a patent. Applying for it would mean that the technology is leaked. Do you know how to deal with this technology? I wonder if it can be transferred.

Could you please help me see if I can transfer it? It’s useless to just have the technology. It still makes sense to have the funds for mass production. "Wang Xu immediately expressed his position.

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

You need to consider the design of special equipment, so don’t rush it yet.

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

With achievement certification, it can be transferred even without applying for a patent.

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

(Popular science: There are four methods to confirm single crystal copper, X-ray diffraction, observing diffraction patterns, high-power microscope observation, observing crystal phase, compression test, and resistivity test. Both of them look at the consistency in all directions)
