Abstract (en)
[origin: EP3225711A1] A method for forming an amorphous alloy member. In the method, within a temperature range from the liquidus temperature to the glass transition temperature in the solidification process of a molten amorphous alloy, low-pressure precision forming is carried out for the amorphous alloy. The method makes use of a smooth, free surface formed after the molten alloy solidifies, good deformation property and low shrinkage coefficient during solidification, to obtain an amorphous alloy member that has high dimensional precision, high surface smoothness and a compact structure without defects such as shrinkage cavities and shrinkage porosity. The method features a short technological process, high production efficiency, and reduced costs.
