摘　　要：采用熔体反应法———液态模锻成形工艺,制取了Al3Zr与Al2O3颗粒共同增强的铝基复合材料。结果表明:通过该工艺成型的复合材料组织致密,无气孔、缩孔等铸造缺陷;相对于金属模成形的复合材料,其抗拉强度提高了127%,耐磨性及伸长率也都有较大地提高,力学性能较好。Aluminum matrix composite reinforced by both Al3Zr and Al2O3 particles were fabricated by direct melt reactions and liquid-forging method. Results indicatthat the composite prepared by this method has compact structure without blowhole and shrinkage cavity. Compared with the composite prepared by die casting, this composite＇s tensile strength increases 127%, wear resistance and elongation have obvious increase, and the mechanical property is better.
