Title:
SUPER SHORT PERIOD NICKEL-ALUMINUM-BRONZE ALLOY HAVING HIGH-STRENGTH AND HIGH-DUCTILITY, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/133680
Kind Code:
A1
Abstract:
A method for preparing a nickel-aluminum-bronze alloy, comprising: mixing Cu, Al, Ni, Fe and Mn powders according to a ratio, melting, forging and thermally treating the powders to obtain a bar, treating the bar by using plasma electrode atomization to obtain an alloy powder, using a selective electron beam melting process to perform 3D printing to obtain the alloy. The internal precipitate phase of the alloy is fine and evenly dispersed, the alloy having high density, and having high strength and high ductility.
