【Abstract】 Several metallurgical factors,which include modificationn treatment, compositions and small quantity of additional elements such as Pb, Bi, were discussed on the effects of machinability of hypereutectic Al~20%Si alloys. The results indicate that the machinability of alloys can be improved considerably by optimization above factors.更多还原
