摘　　要：ZL114合金具有很高的力学性能和很好的铸造性能,广泛的应用于航空航天以及民用工业领域。采用正交实验法,研究浇注温度、模具温度、变质处理温度和变质剂加入量等四个工艺参数对金属型铸造ZL114合金力学性能的影响。结果表明,影响其力学性能的主要工艺参数是浇注温度和变质处理温度,综合力学性能最佳的工艺参数是浇注温度为700℃,变质处理温度为720℃,变质剂加入量为1%和模具温度为250℃。Due to excellent mechanical properties and good castability, ZL114 alloy is widely used in the aerospace and civil industry. The effect of pouring temperature, mold temperature, modifying temperature and modificator addition on the mechanical properties of permanent mold casting ZL114 alloy was studied through orthogonal experimental method. The results show that pouring temperature and modifying temperature are the main parameters to affect the mechanical properties of permanent mold casting ZLl14 alloy. The optimum pouring process parameters, modifying temperature, modificator addition and mold temperature are 700 ℃, 720 ℃, 1 wt% and 250℃, respectively.
