Method for forming amorphous alloy part

Abstract

A method for forming an amorphous alloy part, including: placing a master alloy on a melting platform; heating and melting the master alloy under vacuum to yield an alloy melt; stopping heating and allowing the alloy melt to cool to a temperature between a glass transition temperature and a liquidus temperature thereof; and press-forming and cooling the alloy melt, to form the amorphous alloy part.

The invention claimed is: 
     
         1 . A method for forming an amorphous alloy part, the method comprising:
 1) placing a master alloy on a melting platform;   2) heating and melting the master alloy under vacuum to yield an alloy melt;   3) stopping heating and allowing the alloy melt to cool to a temperature between a glass transition temperature and a liquidus temperature thereof; and   4) press-forming and cooling the alloy melt, to form the amorphous alloy part.   
     
     
         2 . The method of  claim 1 , wherein the master alloy is prepared by smelting or casting; the master alloy is in a shape of rod, plate, flake, or sphere; and a weight of the master alloy is determined by a shape and a size of the amorphous alloy part. 
     
     
         3 . The method of  claim 1 , wherein the vacuum is a pressure of between 1×10 −6  and 1×10 −1  Pa. 
     
     
         4 . The method of  claim 1 , wherein the melting platform does not react with the master alloy and has no influence on melting and solidification of the master alloy. 
     
     
         5 . The method of  claim 1 , wherein a heating mode of the master alloy is electric arc heating, induction heating, resistance heating, laser heating, plasma heating, infrared heating, or microwave heating. 
     
     
         6 . The method of  claim 1 , wherein in 4), a cooling rate of the alloy melt is between 10 −2  and 10 2  K/min.
