Metal matrix composites from dynamic consolidation of powder mixtures
Mixtures of 2124 aluminum alloy and silicon carbide powders were dynamically consolidated using explosives. This process results in a fully dense product and has the potential of becoming an economical method of producing metal matrix composites, especially where undesirable reactions would normally occur between the metal and ceramic reinforcement. With the correct processing parameters, the aluminum powder plastically deforms to form a continuous matrix with minimum interaction with SiC. Microstructure and mechanical properties of the composite are presented. Numerical simulations were performed to better understand the consolidation process and determine test parameters difficult to obtain by experimentation. 7 refs., 3 figs., 2 tabs.
