Description

technical field [0001] The invention relates to the field of new amorphous alloy materials, in particular to a zirconium-based amorphous alloy with a wide supercooled liquid phase region. Background technique [0002] Amorphous alloy is an alloy material formed by the rapid solidification of the melt at a very high cooling rate, thereby preventing the formation of the crystal phase, and freezing the disordered and chaotic atomic configuration of the melt. Amorphous alloys have the characteristics of long-range disorder and short-range order in structure. Due to the unique structural characteristics of amorphous alloys, they can exhibit many properties different from crystalline alloys, such as high strength, high hardness, low magnetic loss, wear resistance and corrosion resistance. [0003] Zirconium-based amorphous alloys have the characteristics of strong glass-forming ability, low critical cooling rate, and wide supercooled liquid phase region. Even with less complicate...
