Aluminum matrix composite powder

摘要

Disclosed herein is an aluminum matrix composite powder comprising 1 to 40% by weight of ceramic particles dispersed in a matrix of aluminum-silicon alloy. The matrix of the composite may further comprise at least one of Cu, Mg and transition metals. The aluminum matrix composite is prepared by a rapid solidification. In the aluminum matrix composite, the ceramic particles are very uniformly dispersed in the matrix, thereby the improvement of mechanical properties of product prepared therefrom can be obtained.
