Titanium sponge had to be remelted in an electric furnace to become a viable ingot, and titanium was active at high temperatures and difficult to process. Pure titanium is very soft and generally not suitable for use as a titanium product, so other elements need to be reintroduced. For example, the titanium 64 commonly used in the aviation industry should be mixed with many other elements to improve the metal performance. (I don't know what to add.) titanium is hard to machine. It's not hard, but it's sticky. I used a file to file the ti-64 handle, and the pattern of the file was quickly filled with slag. It is said that because the speed is too low titanium can not be peeled at all, and if the speed is too high, titanium will be oxidized, and ordinary processing center can not process titanium alloy products at all. Titanium is even harder to make. The frames are very thin and require a lot of fine processing, which is definitely a challenge for titanium, a particularly difficult material to process. In addition, titanium alloy frames also involve titanium alloy welding technology, which is more difficult. How difficult is the technology of titanium alloy processing? Let's just say that the people who design airplanes all over the world, as long as they can use aluminum alloy through structural optimization, will definitely not use titanium alloy, because titanium alloy processing is so difficult. How difficult is it for titanium alloy to weld metal? Until now, MAO and the United States and the titanium alloy welding technology pass, can be used in the aircraft. Oh, yes, my rabbit also got the titanium alloy welding technology from MAO, which is said to be good now. MAO zi's titanium alloy welding technology is good, titanium ore is also more, so made several submarines with titanium alloy, the maximum depth of more than 1000 meters, so far, the world's first.
High strength titanium alloy refers to titanium alloy whose tensile strength is between 1100 and 1400MPa at room temperature. The first to be used in industry is Ti13V11Cr3Al substabilized bionic titanium alloy, whose tensile strength at room temperature reaches 1350MPa. Later, Ti15V3Cr3A13Sn, a cold-formed plate titanium alloy, and Ti8V6Cr4Mo3A14Zr, a semi-stabilized bionic high strength titanium alloy, are developed.
