Titanium is not actually a rare substance because it is the ninth most abundant element and the fourth most abundant structural metal in the earth’s crust, surpassed by aluminum, iron and magnesium. Unfortunately, it is rare Found in high concentrations, it has never been found in a pure state. Therefore, the difficulty of metal processing makes it expensive. Even today, it’s only in Mass production process, and there is no continuous process like other structural metals.
Titanium usually occurs in ore containing ilmenite (fatio3), which is located in the Ilmen Mountains of Russia, or rutile (tio2) on beach sands from Australia, India and Mexico. Titanium dioxide is a very versatile white pigment used in Paint, paper and plastic consume most of the world’s production. In addition to Russia, Australia, India and Mexico, viable deposits include sites in the United States, Canada, South Africa, Sierra Leone, Ukraine, Norway and Malaysia.
Of the 112 chemical elements in today’s known periodic systems, about 85% are metals or metals. There are several ways to classify metals, such as As ferrous or non-ferrous metals, ingots or sintered metals, light metals or heavy metals.
Titanium is classified as non-ferrous metals and light metals. The properties of a metal are essentially based on the metal bonds of the atoms in the crystal lattice. This means free, mobile price electrons The plaid leads to the leisure section. Carbon fiber reinforced plastics have higher specific strength than titanium alloys at temperatures below 300 C (Fig. 1.2). At higher temperatures, the specific strength of titanium alloys is particularly attractive. However, maximum temperature is limited by its oxidation behavior. Since titanium aluminum partially overcomes this disadvantage, they have become a hot topic in the development of alloys. Although the temperature of the traditional high-temperature titanium alloy does not exceed 500C, Titanium-based alloys compete directly with mature high-temperature steels and nickel-based superalloys
