摘　　要：采用脉冲磁场技术制备3003/4004复层铸锭,使用金相显微镜、扫描电镜及电子探针等手段对铸锭的复层界面进行分析检测。结果表明,经脉冲磁场处理的复层铸锭,内层凝固组织由树枝晶向非树枝晶转变,并且界面附近出现大量α-AlMnSi颗粒。A new method using pulsed magnetic field(PMF) to produce cladding ingots of 3003 and 4004 aluminum alloy was investigated.The interface region of the cladding ingots was studied by optical microscope,scanning electron microscope and electron probe microanalysis.The results indicate that in the PMF,the inner layer solidification structure of 4004 alloy changes from dendritic crystals to cellular grains.It is also observed that there appear lots of α-AlMnSi particles near the interface of 3003 and 4004 alloy when PMF is imposed.
