摘　　要：ZL102合金的铸造性能良好,但力学性能较低。通过液态模锻工艺得到的ZL102制件,其力学性能比金属型铸造制件提高,组织细化。文章讨论了制件施加不同的压力及选择不同的工艺参数,对其组织和力学性能的影响。施加60kN的力时,组织细密,抗拉强度很高,耐磨性好,但同时塑性却相对较低;合金浇注温度在640℃时,强度最高,抗拉强度以及拉伸率等则随模具预热温度的升高,而呈现不规则的下降趋势。Casting property of ZL102 alloy is good, but mechanical property is very ecumenical. The mechanical property of ZL102 alloy obtained by liquid forging process is better than the metal-die casting, and the microstructure is fine. The effect of technological parameters on the microstructure and mechanical properties of liquid forged ZL102 alloy is discussed in this paper. When the pressure of 60 kN is applied, the microstructure is minute, and ultimate tensile strength and wear-resisting property is perfect but at the same time the plasticity is low; When alloy pouring temperature is 640 ℃, the strength is high~ ultimate tensile strength and elongation present anomalistic descent when die preheated temperature ascend.
