Metal matrix composites made by spray forming

TLDR: In this paper, a comparison with the equivalent materials made by powder metallurgy or by the melt mixing route is made, and it is shown that metals matrix composites made by spray forming can incorporate both of these benefits in one operation.

Abstract: Spray-formed metals have a finer structure, near zero segregation and improved mechanical properties resulting from rapid solidification, when compared with conventional materials. A further benefit of spray forming is that it gives greater freedom to add any second or third phase, liquid of solid, by entraining a stream of the added phase into the atomized spray before deposition. This paper shows that metals matrix composites made by spray forming can incorporate both of these benefits in one operation. A comparison with the equivalent materials made by powder metallurgy or by the melt mixing route is made.
