Abstract

The invention discloses a low-cost high-strength high-plasticity zirconium-based amorphous composite. The formula of the low-cost high-strength high-plasticity zirconium-based amorphous composite is Zr58.5Ti14.3Nb5.2Cu6.1Ni4.9Be11.0. A preparation method comprises the following specific steps of A, preparing materials, wherein Zr, Ti, Nb, Cu, Ni and Be metal raw materials are weighed and fetched according to the composition and atomic percent of Zr58.5Ti14.3Nb5.2Cu6.1Ni4.9Be11.0; B smelting master alloy, wherein a vacuum arc furnace water cooling copper crucible smelting method is adopted, theabove metal raw materials are smelted into uniform master alloy ingots; C forming the composite, wherein a vacuum die casting metal die formation rapid cooling method is adopted, the master alloy ingots are made into a casting of the zirconium-based amorphous alloy composite. The low-cost high-strength high-plasticity zirconium-based amorphous composite solves the problems that an existing zirconium-based amorphous alloy is poor in indoor temperature plasticity and high in raw material cost; the prepared zirconium-based amorphous alloy composite is low in cost and high in strength and indoortemperature plasticity and can be applied to industrial production.

Description

Technical field [0001] The invention relates to an amorphous composite material and a preparation method thereof, in particular to a low-cost high-strength room temperature plastic zirconium-based amorphous alloy composite material and a preparation method thereof, and belongs to the technical field of amorphous alloy composite materials. Background technique [0002] At present, because of its unique microstructure, bulk amorphous alloys have excellent properties that crystalline alloys (traditional metals) cannot match, such as high strength, high hardness, high elasticity, high fracture toughness, and excellent corrosion and wear resistance. It has great application value and prospects in consumer electronics, sports equipment, medical equipment, military industry, aerospace and automotive industries. However, most bulk amorphous alloys form highly localized shear bands during the room temperature load-bearing deformation process. Further deformation will cause the shear bands...
