Al2O3／ZL109复合材料显微组织特性

摘要

Because of the good mechanical properties and relatively low product cost, aluminium alloy matrix composites containing short alumina fibre reinforcement have recieved great research abroad recently, but up to now, litte has been done at home. In this paper, the general microstructural features of the Al_2O_3/ZL109 composites fabricated with squeese infiltration technique are present and interpreted.
