An apparatus and method for directional processing of reinforced metal matrix composites

Abstract

This invention provides a directional processing apparatus and method for reinforced metal matrix composites, comprising: a powder bundle cylinder; and a directional powder spreading structure including a drive assembly, a rotating shaft, and an impeller assembly. The impeller assembly is disposed within the powder bundle cylinder. One end of the rotating shaft is fixedly connected to the impeller assembly, and the other end of the rotating shaft extends out of the powder bundle cylinder and is connected to the drive assembly. The drive assembly can drive the rotating shaft to rotate and move vertically. The impeller assembly has multiple dispersion gaps. When alloy powder is conveyed into the powder bundle cylinder, it moves vertically as the rotating shaft drives the impeller assembly to rotate. The alloy powder passes through the corresponding dispersion gaps and forms a powder bed at the bottom of the powder bundle cylinder. Simultaneously, the two-dimensional reinforcing phase powder entering the corresponding dispersion gaps can be directionally distributed within the powder bed under the shear force of the impeller assembly. This apparatus solves the problem of the difficulty in achieving directional distribution of the two-dimensional reinforcing phase during powder metallurgy forming.
