Embodiment Construction

[0013] The inventors have found through a large number of experiments that when the oxygen content is high, the amorphous forming ability of the amorphous alloy will be correspondingly weakened and the brittleness will be enhanced. When the oxygen content in the alloy increases from 590ppm to 3000ppm, the critical cooling rate of the alloy increases by at least one order of magnitude. Oxide-induced heterogeneous nucleation in alloy melts is the main reason why oxygen reduces the glass-forming ability of bulk amorphous alloys. Moreover, the inventors also found that oxygen tends to segregate and enrich in the pro-eutectoid crystal, and the microcosmic mechanism of oxygen action is based on the influence of crystal nucleation in the supercooled melt of the alloy. Therefore, oxygen has an adverse effect on the glass-forming ability shown in the cooling and solidification process of the amorphous alloy melt and the thermal stability shown in the heating process after obtaining the...

Abstract

The invention relates to a recovery method of zirconium based amorphous alloy, comprising the following steps: a. rust removal, oxide removal and degreasing treatment are carried out to a zirconium based amorphous alloy scrap; b. the processed scrap and additives containing rare earth elements are mixed according to proportion, and the mixture is vacuum-melted; c. the temperature of the melted mixture is reduced to 100-200DEG C above the melting point of the mixture, and then the temperature is insulated; d. the mixture is vacuum-melted again, the melted mixture is injected into a copper moldand is cooled under the protective gas, thereby obtaining the amorphous alloy ingot. The recovery method of zirconium based amorphous alloy can effectively reduce the oxygen content in the amorphous alloy scrap; meanwhile, the bending strength of an amorphous alloy sample can be effectively improved, so as to increase the critical size of the amorphous alloy sample.

Description

technical field [0001] The invention relates to a recovery method of an amorphous alloy. In particular, it relates to a method for recovering zirconium-based amorphous alloys. Background technique [0002] Due to its special structure - long-range disorder and short-range order, amorphous metal materials have excellent properties: high strength and hardness, wear resistance, corrosion resistance, large elastic limit and high electrical resistance. performance, but also exhibits excellent superconductivity and low magnetic loss. Therefore, amorphous metal materials are recognized as the most potential new structural materials, which are widely used in many fields such as machinery, IT electronics, and military industry. . The emergence of bulk amorphous materials has greatly promoted the research and application of non-gold materials. Among the currently known amorphous systems, there are still relatively few component systems that have both good amorphous formation abilit...
