Abstract

The invention belongs to the preparation technique of amorphous alloy composite powder and discloses Cu<50>Zr<40>Ti<10> / Cu<2>O amorphous alloy flake composite powder and a preparation technology thereof. The Cu<50>Zr<40>Ti<10> / Cu<2>O amorphous alloy flake composite powder is characterized in that the composite powder is formed by authigene Cu<2>O crystalline grains uniformly distributed in a Cu<50>Zr<40>Ti<10> flake amorphous alloy basal body. The preparation technology comprises the following steps: 1 compounding lump Cu, Zr and Ti with purity of 99.99wt% according to composition proportion of at% as Cu<50>Zr<40>Ti<10>, putting the compound materials into a crucible of an electric-arc furnace, and smelting the materials for six times to obtain mother alloy; 2 by adopting an atomization method, atomizing the mother alloy into spherical amorphous alloy powder; 3 putting the powder into a stainless steel ball-milling pot, and pouring absolute ethyl alcohol into the ball-milling pot for covering the powder and grinding balls completely; 4 under the condition of ball-milling speed of 500 r / min, conducting ball milling for 40 h, and obtaining the flake amorphous alloy composite powder.

Description

technical field [0001] The present invention relates to a Cu 50 Zr 40 Ti 10 / Cu 2 O amorphous alloy flake composite powder and its preparation process. Background technique [0002] Copper-based bulk amorphous alloys have excellent physical, chemical, and mechanical properties, but their room temperature brittleness and limited size limit their industrial applications. Composite materials can solve the problem of room temperature brittleness. In theory, powder metallurgy can realize the preparation of infinite bulk amorphous alloys and their composite materials, but the preparation of high-quality amorphous alloy powders or amorphous alloy composite powders is one of the key issues in powder metallurgy. Contents of the invention [0003] The object of the present invention is to provide a kind of Cu 50 Zr 40 Ti 10 / Cu 2 O amorphous alloy flake composite powder and its preparation process. [0004] The purpose of the present invention is achieved by the following t...
