Abstract
The effect of four different Hot Isostatic Pressing (HIPping) treatments on porosity in the aluminium casting alloy A357 and stir-cast A357/15 vol% SiC particulate MMC has been investigated and the optimum treatment identified. The bend strength increased after HIPping relative to as-received. Such ceramic particle reinforced MMCs, however, do not have adequate toughness for many commercial applications. Metal reinforced MMCs made by combining an Al alloy matrix with stainless steel wire can provide a compromise between weight saving and toughness. The production, involving HIPping, of such a composite is discussed.
