Abstract

Aluminum based Metal Matrix Composites (MMC's) are being considered for many different high volume applications. The most common manufacturing rout for aluminum based MMC's is a blend/can/extrude route. This route is considered high cost and not practicable for high volume applications such as automotive parts. Interparticle spacing is though to be an important factor on mechanical properties. Where little or no hot work occurs in the manufacturing process, the starting particle size distribution of the metal powder should have a significant effect on the resulting microstructure and mechanical. This work examines the relationship between metal powder size, SiC size and the resulting microstructure and mechanical properties for pressed and sintered compacts.
