Abstract

A zirconium-based amorphous alloy and a preparation method therefor. The composition of the amorphous alloy is ZraCubAlcMd(Er1-xYx)e, wherein M is at least one selected from Ni, Fe, Co, Mn, Cr, Ti, Hf and Ta, 40≤a≤70, 15≤b≤35, 5≤c≤15, 3≤d≤15, 0.2＜e≤2.5, and 0＜x＜0.5, and the amorphous alloy is obtained by smelting and cooling molding under the protection of an inert gas or a vacuum condition.

Description

technical field [0001] The invention relates to a zirconium-based amorphous alloy and a preparation method thereof. Background technique [0002] Amorphous alloys appeared in the 1960s. The initial amorphous alloys are difficult to be practically applied because the critical size (the largest size for forming amorphous crystals) can only reach the micron level. However, the material properties of amorphous alloys such as high strength, high hardness, corrosion resistance, and excellent high-temperature fluidity have attracted numerous researchers to carry out continuous research, and have successively developed amorphous alloys with large critical sizes and suitable for industrial production. Crystalline alloys, whose critical size gradually develops from the micron level to the millimeter level and even to the centimeter level. Generally speaking, amorphous alloys whose critical cooling rate is less than 500°C / s and whose critical size is greater than 1 mm are called bulk...
