摘　　要：主要研究在ZL107合金中加入0.05%的FeBSi非晶合金,通过不同时间细化变质对ZL107合金铸态和热处理后组织与性能的影响。结果表明,加入0.05%的FeBSi非晶合金后ZL107合金的抗拉强度和伸长率明显增加,其中保温时间为30 min时,合金抗拉强度和伸长率分别为453.41 MPa和14.2%,比未加非晶合金的分别提高了24.7%和65.7%,加入0.05%的FeBSi非晶合金后ZL107合金的α-Al和共晶Si明显细化,主要强化机制为细晶强化和第二相强化。The effects of 0.05%FeBSi amorphous alloy with different inoculation time on the microstructure and mechanical properties of as-cast and heat treated ZL107 were investigated.The results show that the tensile strength and elongation of the ZL107 alloy are increased significantly with the addition of 0.05%FeBSi amorphous alloy.The tensile strength and elongation of ZL107 with inoculation time of 30 min reach 453.41 MPa and 14.2%respectively,which is 24.7%and 65.7%higher than the ZL107 without FeBSi amorphous alloy,respectively.Theα-Al and eutectic Si in ZL107 alloy are refined obviously after the addition of 0.05%FeBSi amorphous alloy,which is attributed to grain refinement strengthening and secondary phase strengthening.
