摘要 本工作以AlSi10MnMg为基础合金,通过添加Sr、Er的方法对合金进行复合变质处理,研究不同添加量下Sr、Er对AlSi10MnMg合金微观组织、导热性能、力学性能的影响规律,力图实现AlSi10MnMg合金导热、力学性功能一体化。结果表明:在金属型铸造工艺下,添加Sr能够有效改善合金中共晶Si形貌,在此基础上添加稀土元素Er能够在改善共晶Si形貌的同时进一步细化共晶Si。此外,Sr、Er能够细化AlSi10MnMg合金中α-Al的二次枝晶间距,进而提升合金的导热性能及力学性能。当添加0.05%Sr+0.3%Er时,合金变质效果及性能提升最显著,相比未变质的合金,其二次枝晶间距降幅达到67.3%,共晶Si长宽比降幅达到46.1%。性能方面,合金导热率提升17.4%,达到179.32 W/(m·K);磨损性能提升11.2%;抗拉强度提升34.58%,达到221.96 MPa;伸长率提升104.48%,达到15.97%。

Abstract: In this work, AlSi10MnMg was used as the base alloy, and the alloy was subjected to compound modification treatment by adding Sr and Er. The influence of Sr and Er on the microstructure, thermal conductivity and mechanical properties of AlSi10MnMg alloy under different additions was studied, to realize the integration of thermal conductivity and mechanical function of AlSi10MnMg alloy. The results show that the addition of Sr can effectively improve the eutectic Si morphology of the alloy under the metal mold casting process. On this basis, the addition of rare earth element Er can improve the eutectic Si morphology and further refine the eutectic Si. In addition, Sr and Er can refine the secondary dendrite arm spacing of α-Al in the AlSi10MnMg alloy, thereby improving the thermal conductivity and mechanical properties of the alloy. Compared with the unmodified alloy, the secondary dendrite spacing decreased by 67.3%, and the eutectic Si aspect ratio decreased by 46.1%; in terms of performance, the thermal conductivity increased by 17.4% to 179.32 W/(m·K); the wear performance improved 11.2%; tensile strength increased by 34.58% to 221.96 MPa; elongation increased by 104.48% to 15.97%.
