Description

technical field [0001] The invention relates to a Ti-based amorphous alloy containing P element and a preparation method thereof, belonging to the technical field of new materials. Background technique [0002] Amorphous alloys refer to metal alloys whose atomic arrangement is characterized by long-range disorder and short-range order. Because the structure of amorphous alloy is the same as that of oxide glass, it is also called metallic glass. Unlike the periodic symmetry and anisotropy of the atomic arrangement of traditional crystalline alloys, the atomic arrangement of amorphous alloys is characterized by non-periodic symmetry and isotropy. Dislocations and grain boundaries in crystalline alloys also do not exist in amorphous alloys. The special structure makes amorphous alloys have different mechanical, physical and chemical properties from crystalline alloys. [0003] The metal melt has a tendency of spontaneous nucleation and crystallization during the solidificati...
