摘要:
在Al-Mg-Si合金中添加稀土和钛,采用OM ,SEM和EDS对合金显微组织进行分析,并通过性能测试,研究稀土和钛对Al-Mg-Si导体材料组织和性能的影响．研究表明;RE和Ti对Al-Mg-Si导体材料均有细化作用.当合金中RE和Ti质量分数分别超过0.3%和0.15%时,稀土元素Ce和Ti发生反应，生成Al Ti,Ce相,消耗熔体中大量的Ti和Ce ,对合金的力学性能和导电性能有不利影响.
Abstract:
We added rare earth and titanium in Al-Mg-Si alloy,and the influence of rare earth and titanium onthe microstructure and properties of Al-Mg-Si conductive material were studied in this paper,with the opticalmicroscope,scanning electron microscope,DSC analysis on the microstructure of alloy,and testing the per-formance. The results show that,RE and Ti both have refining effect on Al-Mg-Si conductive material. Whenthe content of RE is more than 0.3% and the Ti is more than 0.15%,the phase Al Ti,Ce will form in Al-Mg-Si alloy,consuming a large amounts of Ti and Ce,which has an unfavorable effect on the mechanicalproperties and electrical conductivity of the alloy.
