A Study of Mechanical Alloying of an Aluminum Composite Material Reinforced with Silicon Carbide Particles

Abstract

A composite material based on alloy V95 containing 10% silicon carbide and prepared by powder metallurgy is studied. Composite granules are fabricated by mechanical alloying in a planetary mill in an inert gas atmosphere. It is shown that the structure of the composite granules affects the structure of the billets obtained after deformation treatment by extrusion, i.e., the more homogeneous the structure of the granules, the more homogeneous is the bar structure.
