was named by Wang Liheng, Zhang Jiawei was really surprised, as a named student, if he couldn't ask a decent question, he would definitely laugh off his big teeth, especially in front of the beautiful sister.

Zhang Jiawei greeted Wang Liheng's ancestors for the eighteenth generation in his heart, but his butt could only reluctantly leave his seat.

Looking at Zhang Jiawei's confused look, Wang Liheng couldn't help but be happy in his heart, and looked at Zhang Jiawei with the mood of watching jokes.

Zhang Jiawei coughed, cleared his throat, and asked, "Senior Sister Zhao, you are an expert in material mechanics, and you must have some understanding of materials." I have a question, the development and change of new industries and technologies have also put forward innovative requirements for the preparation of raw materials, how to view the impact of new technologies represented by laser forming technology on the demand for traditional steel materials? ”

After Zhang Jiawei asked the question, Wang Liheng was stunned, he actually couldn't understand what Zhang Jiawei was saying, so his intuition made him feel that this guy was purely talking nonsense, so he suddenly showed a displeased look on his face, stood up and said: "Zhang Jiawei, don't deviate too much, it seems that you are..."

"No, listen to him." Zhao Zhiying interrupted Wang Liheng's words with a solemn face, stared at Zhang Jiawei in the back half of the classroom with a pair of good-looking eyes, and asked in surprise: "Zhang Jiawei, right, do you know laser forming technology?" ”

In fact, where did Zhang Jiawei know about laser forming technology, these are some information he just learned from the origin system. After Wang Liheng asked him to ask a question, Zhang Jiawei knew that Wang Liheng wanted him to make a fool of himself, so he didn't let him succeed and exchanged some knowledge related to aircraft engines and aircraft composite materials to the origin system, and then raised this question.

Seeing Zhao Zhiying asking, Zhang Jiawei nodded.

After receiving an affirmative reply, Zhao Zhiying said in surprise: "Students, I am very surprised, I didn't expect that someone in our undergraduate class of mechanics would know about laser forming technology. However, it is a pity that I do not study laser rapid prototyping technology, and I know very little, so I can't comment on it, and I can only say that I have a one-hole opinion. Laser rapid prototyping is a good way to imitate, prototype components, and turn molds. However, it is not clear that it is used for aviation components, especially the outstanding advantages of key components. The biggest advantage of laser rapid prototyping should be that it is fast, the equipment is simple, and it is not limited by the size and shape of the component, which can be used as a supplement to the traditional part technology. However, foreign test data show that the fatigue life of laser forming AERMET100 steel components is higher than that of castings and lower than that of forgings, which is in line with scientific principles. From the rapid solidification of the liquid state, the strengthening mechanism of the workpiece needs to be newly understood. Aerospace components emphasize reliability and require stable mass production and inspection data, while laser forming is still a single piece of prepared components. Laser forming requires metal powder raw materials, and it is difficult to reduce the cost of parts. It should be said that laser forming technology has a broad space for development and other application prospects, and it needs to be further understood and studied for aviation components. It should also be said that laser forming is not a technology for the preparation of metallic materials, it does not have a melting process. ”

Zhang Jiawei listened to Zhao Zhiying's words, shook his head, and did not speak.

Zhao Zhiying saw Zhang Jiawei shaking her head, and asked with some doubts: "Doesn't Zhang Jiawei agree with my point of view?" ”

Zhang Jiawei nodded and said, "Senior Sister Zhao, I do disagree with your point of view. What you say is true, but what you say is wrong. It is true that this technology has been developed for more than 20 years since the development of laser forming technology in the 80s of the last century, but I think that human research on this technology is still in a preliminary stage. I've seen some material about this, and I've made some assumptions......"

Speaking of which, Zhang Jiawei began to elaborate on what he had just exchanged from the Origin System, and started a discussion with Zhao Zhiying. As soon as the two opened the chatterbox, they couldn't hold it back, Zhao Zhiying was still sitting at first, but when she got to the back, she simply stood up and talked eloquently, until the bell rang after class, she was still unsatisfied.

Wang Liheng didn't dare to interrupt them, so he could only let them continue to talk, until later, after Zhao Zhiying came to her senses, she suddenly stopped abruptly, closed the topic, and said with a hint of self-deprecation: "I'm sorry for delaying everyone's time after class, Zhang Jiawei, I didn't expect you to have such a deep understanding of laser forming technology, which surprised me very much and gave me a lot of inspiration." If you are interested, please contact me after class to discuss. ”

After class, Zhang Jiawei immediately became the focus of attention and became the object of invitation to the beautiful sister, which is not a treatment that ordinary students can enjoy, and Wang Liheng, who has an empty bamboo basket, is even more dissatisfied.

"Phew, bumped into shit luck, with your half-ass, do you really think you can communicate with Senior Sister Zhao?" Seeing Zhang Jiawei silently packing up his notebook, Wang Liheng couldn't help but come over and said sarcastically.

Zhang Jiawei looked calm, stared at Wang Liheng, and provoked unexpectedly: "What's the matter? You bite me? ”

Wang Liheng has never given him a good look, so he naturally won't pretend to be a color to him.

Wang Liheng couldn't do anything about Zhang Jiawei, so he could only glare at her and leave.

"Boss, let's go to the 'hot spot' now?" Zheng Silin asked Zhang Jiawei while packing up his notes.

"No, you go first, I still have something to do." Zhang Jiawei looked at Zhao Zhiying on the stage, at this moment she was surrounded by enthusiastic classmates, everyone was discussing enthusiastically, the lecture was over, and some other students began to slowly leave.

"Then ......" Zheng Silin was worried, if the boss didn't leave, how could he go.

"It doesn't matter, I'll be there later." Zhang Jiawei closed the laptop and put it back in his bag.

"Okay, then I'll go first, I'll see the boss later." Zheng Silin left with doubts.

Zhang Jiawei is still waiting, he doesn't know if it is appropriate for him to find Zhao Zhiying in the past, the classmates around her are actively asking her questions, Zhao Zhiying looks very enthusiastic, but she can't hide her tiredness, yes, they have made speeches for more than an hour, and anyone will be tired.

Zhang Jiawei noticed that Professor Gong was also behind her, and everyone was talking and laughing. Finally, the time was not early, and those classmates also said goodbye and began to leave. Zhang Jiawei also walked out of the lecture hall with the flow of people, he thought twice, and decided to get in touch with Zhao Zhiying after knowing more about her.

But not long after he walked out of the lecture hall, Zheng Silin's phone called.

"Excuse me, Boss, did you leave the lecture hall?" Zheng Silin asked.

"Just came out, what's the matter?"

"No, I left the key in the seat, could you please help me get it?"

"Well, okay, where did you put it?"

"It's just under the table, there are a lot of things on the table just now, so I put it in, you see my memory, I forgot to take it when I left, boss, please."

"It's fine." Zhang Jiawei smiled, then turned his head and walked back to the lecture hall.

Back in the classroom, except for a few students who were still copying notes, Professor Gong and Zhao Zhiying were gone, Zhang Jiawei returned to the seat he had just sat in and got the key that Zheng Silin had left behind.

Walking downstairs, he saw Zhao Zhiying saying goodbye to Professor Gong from a distance, and then she walked slowly on the campus path, he smiled and shook his head, and wanted to follow again, but at this time his mobile phone rang, picked it up and looked, it turned out to be Wu Shanshan.

"Phew, bumped into shit luck, with your half-ass, do you really think you can communicate with Senior Sister Zhao?" Seeing Zhang Jiawei silently packing up his notebook, Wang Liheng couldn't help but come over and said sarcastically.

Zhang Jiawei looked calm, stared at Wang Liheng, and provoked unexpectedly: "What's the matter? You bite me? ”
