Crack avoidance during powder metallurgy of a SiC particel reinforced aluminium alloy A 6063

Abstract

Light alloys compounds are gaining increasing importance as compared to non-reinforced matrix materials. The present contribution highlights the powder metallurgical fabrication of a alumiunium alloy reinforced with silicon carbide. Quite good results were achieved by addition of 12 volume percent silicon carbide. In the scope of the investigations also the cast and forming temperatures were optimized to achieve an optimum distribution of the silicon carbide during production of the compounds.
