The invention relates to a preparation method for a
zirconium-based amorphous
alloy as well as
powder and a large-sized block of the
zirconium-based amorphous
alloy, which belongs to the field of amorphous alloys, and is characterized by comprising the component of Zr61(Cu, Ni)27.5Al10Re1.5(at%), wherein Re is Y, La, Ce, Nd, Gd and Er, and adopting a manner of combination of the gas atomization
powder milling technology and the
spark plasma sintering technology. The preparation method comprises the following steps: preparing raw materials according to components of the amorphous
alloy, and placing the raw materials into an induction
crucible of gas atomization
powder milling equipment; vacuumizing and filling
inert gas for shielding;
smelting to obtain an alloy solution with uniform components under the action of
induction heating; pouring the alloy solution after
smelting into an insulation bag at a
constant speed slowly, and filling high-pressure
inert gas as an atomizing medium at the same time; atomizing the alloy
solution flow into small droplets under the
impact of high-pressure
airflow, and finally cooling to form amorphous alloy powder; collecting and screening the amorphous alloy powder; and under the protection of the
inert gas, utilizing the
spark plasma sintering technology to perform
sintering on the amorphous alloy powder at different temperatures and pressure to obtain an amorphous alloy block.
