Titanium is an important structural metal developed in the 1950s. Titanium alloys are widely used in various fields due to their high specific strength, good corrosion resistance and high heat resistance. Many countries in the world have recognized the importance of titanium alloy materials, and have successively conducted research and development on them and have obtained practical applications. Titanium is a Class IVB element in the periodic table. It looks like steel and has a melting point of 1,672°C. It is a refractory metal. Titanium is abundant in the earth's crust, much higher than common metals such as Cu, Zn, Sn, and Pb. my country's titanium resources are extremely rich. In the super-large vanadium-titanium magnetite discovered in Panzhihua, Sichuan alone, the associated titanium metal reserves are about 420 million tons, which is close to the total proven titanium reserves abroad. Titanium alloys can be divided into heat-resistant alloys, high-strength alloys, corrosion-resistant alloys (titanium-molybdenum, titanium-palladium alloys, etc.), low-temperature alloys, and special function alloys (titanium-iron hydrogen storage materials and titanium-nickel memory alloys) according to their uses.
