摘要：

The machinability of an Al-5 Mg alloy reinforced with 5 vol% Saffil and 15 vol% SiC was compared with that of Duralcan (A356) reinforced with 15 vol% SiC. In terms of tool wear and metal removal rate with both cemented carbide and polycrystalline diamond (PCD) cutting tools, it was found that the Duralcan/BC was significantly easier to machine than the composite with the Al-5 Mg matrix. This is attributed to the effect of the matrix on the mechanisms of abrasion wear. With both metal matrix composites, the performance of PCD was significantly better than that of the cemented carbides.
