Zhang Feng went directly to the second floor, found the heat-resistant alloy research room with familiarity, knocked on the door, and did not wait for the people inside to respond, and directly pushed the door in. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

It was not yet one o'clock in the afternoon, it was still lunch time, and there was only one person in the research room buried his head in front of a large instrument, staring at the screen for a moment, not noticing Zhang Feng's arrival at all.

Zhang Feng walked lightly behind the man and waited quietly, until he finished the experiment and recorded the data, then he coughed and said: "Ahem, Comrade Li Hansheng, people are iron rice and steel, if you don't eat at noon, I will call my sister-in-law when I turn around." ”

Li Hansheng turned around in some surprise, supported the frame of his glasses with his hand, and when he saw Zhang Feng's appearance clearly, he patted him on the shoulder and said with a smile: "Don't, don't, your sister-in-law is a knife mouth." You have a dozen small reports, at least nag me for a few days. Besides, I've asked Xiao Wang to bring food back from the cafeteria. ”

Sure enough, while the two were talking, several young people returned to the research room after eating, and when they saw Zhang Fengzai, they all stepped forward to say hello, one of them took out two lunch boxes, handed them to Li Hansheng, and said: "Li Tou'er, your favorite scallion pork ribs, the spoon in Chef Wang's palm, tastes absolutely authentic." ”

Li Hansheng took the lunch box and thanked him, found a place, sat down, and chatted with Zhang Feng while eating: "Xiao Zhang, I heard that you resigned from Tunghai University. I told you a long time ago that the school is not a place for scientific research, with little funding and backward equipment. How about it, come to 4421 to mess up with your brother Li. ”

Zhang Feng waved his hand again and again and said, "Don't, don't, it's easy to jump out of school, I don't want to jump back into the system." ”

"Then why are you here this time? Looking for Director Chi? It was really unfortunate that Chi Lao went to the capital to hold a seminar. ”

Zhang Feng kicked the trolley box under his feet and said with a smile: "I don't want to see Chi Lao, I came to the research institute to borrow your laboratory to test some metals." ”

Li Hansheng pointed to the equipment behind him with the chopsticks in his hand and said, "It's done here, we only use that electron microscope in the afternoon." ”

Zhang Feng shook his head and said: "Don't, let's go through the regular procedures, I don't want to be scolded by Uncle Chi for digging the corner of socialism for a thousand yuan." ”

"Okay, whatever you want, I'll open a note for you, and you go to the finance department to pay the fee and get the key."

Renting out laboratories can also be regarded as a way for 4421 to generate income, and all kinds of instruments here are relatively complete, and people from schools or other scientific research institutes often come to borrow laboratories. Zhang Feng paid the money and received the key, and he didn't need to be led, so he found the metal performance testing room familiarly.

When I opened the door, I was greeted by the smell of engine oil mixed with rusty steel. Metal performance testing, whether it's ductility, stiffness, toughness, or wear resistance, involves a lot of machinery. As long as there is a mechanical structure, this smell is normal.

I walked to the window and turned on the ventilation fan, and with the whining sound of the fan spinning, the smell was finally not so heavy. Lift the blue cloth that covers the instrument to prevent dust, and a puff of dust rises.

This is the backup testing room of the 4421 Institute, and all the equipment is eliminated from other departments, which is somewhat backward, but only the preliminary testing is enough.

Open the trolley case and take out the blue gold that is the size of a basketball. First on the vacuum smelting furnace, 500 degrees, 1000 degrees, 1500 degrees...... Blue gold is still the same, and as the temperature exceeds 2,000 degrees, Zhang Feng's heart is getting more and more excited. Until the ultimate temperature of the vacuum smelting furnace is reached at 3000 degrees, the blue gold still has no traces of melting, and it has not even turned red.

Zhang Feng clenched his fist with one hand and waved it vigorously, and the excitement in his heart was beyond words. This means that blue gold has good heat resistance, and is likely to withstand temperatures above 1,000 degrees, if it exceeds 1200 degrees, it is a very good super heat-resistant alloy. The resistance temperature refers to the temperature at which the alloy can be used for a long time without metal fatigue and without significant degradation of various properties, which is generally much lower than the melting temperature. Generally, steel is mostly at 600 to 700 degrees, and some nickel-based and niobium-based alloys can be used at a temperature of more than 1000 degrees, which are widely used in aero engines.

In order to make the blue financial, Zhang Feng operated the vacuum furnace to cool down, opened the lid of the furnace, and then took out a handful of fire magic crystal powder and sprinkled it into the furnace. These powders were given when blue gold was bought and were the catalyst for melting the blue gold. Close the lid of the vacuum furnace and continue to heat, just over 1500 degrees, the blue gold has melted into a bright blue liquid, and unlike other metal solutions, the liquid blue gold has a certain permeability, which is very beautiful.

The vacuum furnace continues to be operated to cast test workpieces of various shapes. Wait for it to cool down and test its performance one by one. The results obtained are very good, blue gold not only has excellent heat and corrosion resistance, but also has high high temperature mechanical properties and good microstructure stability. Ideal for high-temperature components in aerospace engines and gas turbines. In particular, its temperature-bearing capacity has reached an astonishing 2000 degrees, compared with the fifth-generation superalloys on the earth that are still tossing at 1200~1400 degrees, Lanjin is simply a Mercedes-Benz sedan compared with a bicycle. Moreover, the density of blue gold is only 4.7, which is much lower than that of steel, and the light weight is the biggest advantage of aero engines.

Compared to its superior high temperature resistance, the machinability of blue gold is too poor, and the Mohs hardness of blue gold is 15, and the corresponding diamond has a Mohs hardness of 10. With a Mohs hardness of 15, there is no turning tool of any material that can process blue gold, and maybe there are still metals that can cut blue gold in the other world, so Zhang Feng needs to go to the other world to continue to search.

It cannot be processed by a lathe, which means that if the turbine disc is made of blue gold, high-temperature parts such as fan blades can only be molded through one-time precision casting, and the mold, process, and process can not make the slightest error, which can be imagined. Fortunately, this kind of technology has been developed in China, and it is not particularly difficult to get it as long as you are willing to spend money, as far as Zhang Feng knows, the 4421 Institute has mastered this technology.

After the performance test, Zhang Feng's mood can only be described as ecstasy. This is followed by elemental analysis of the constituent elements of the material, using a scanning tunneling electron microscope. The results are bizarre: the atomic structure of blue gold is an irregular polyhedron, much like a large number of iron atoms inserted between carbon atoms in the atomic structure of diamond. With such a strange composition, it is supposed that it will collapse quickly, but existence is the truth, and even the shuttle to the other world has appeared, so what else is impossible.

After doing all the tests, Zhang Feng copied the results to a USB stick that he carried with him, and all the data on various instruments and computers were eliminated by Zhang Feng. Doing this is also to prevent the blue gold from leaking too early, after all, this thing is a bit too rebellious, and if you don't do it, it will cause a big disaster.
