[0002] Titanium alloy is an alloy composed of titanium and other elements. Titanium has two isomorphous crystals: titanium is an allotrope with a melting point of 1668℃. It presents a close-packed hexagonal lattice structure below 882℃, called α-titanium; it presents a body-centered cubic lattice structure above 882℃, called β-titanium. By taking advantage of the different characteristics of the above two structures of titanium, appropriate alloying elements are added to gradually change its phase transition temperature and component content to obtain titanium alloys with different structures.
