Abstract

The invention relates to the technical field of amorphous alloys, in particular to a method for rapidly smelting a zirconium-based amorphous alloy master alloy. The method comprises the following steps that a niobium block and sponge zirconium are pretreated to obtain niobium particles and a zirconium electrode; the niobium particles, the zirconium electrode and the rest alloy raw materials are uniformly mixed to obtain alloy raw materials; a crucible is installed in an inductor, baking and vacuumizing are carried out, and the crucible is preheated through coil induction heating; the alloy rawmaterials are added into the crucible, protective gas is introduced, and the raw materials are heated to be molten uniformly through coil heating, poured into a mold and cooled, and therefore the zirconium-based amorphous alloy master alloy is obtained. The raw materials are pretreated, the sponge zirconium is mechanically compacted, zirconium is change from a honeycomb structure to a solid structure, induction melting is facilitated, and ingredient uneven caused by element nonmelting in the melting process can be avoided; the niobium block is crushed into small niobium particles, therefore niobium is easier to melt, and the problem that niobium is not thorough in melting due to the high melting point is solved.

Description

technical field [0001] The invention relates to the technical field of amorphous alloys, in particular to a method for rapidly melting zirconium-based amorphous alloy master alloys. Background technique [0002] Amorphous alloy, also called metallic glass, is usually prepared by rapid solidification of liquid alloy melt, and its internal structure is a long-range disordered amorphous structure similar to glass. The unique atomic arrangement structure of amorphous alloy makes it have many excellent characteristics, such as high strength, high hardness and high wear resistance and so on. [0003] However, in the prior art, due to the large volume of zirconium and the honeycomb structure of zirconium sponge, the magnetic induction coil cannot directly heat the zirconium to melt it. The existing zirconium-based amorphous alloy master alloy is usually melted by adding other alloy raw materials first, and then adding zirconium. , thus avoiding the infusibility of zirconium. Howe...
