采用AZ31镁合金和纯铝进行高温复合轧制制备镁-铝复合板,使其兼具铝的表面耐蚀性和镁合金的高比强度特性.采用金相显微镜、扫描电子显微镜和电子万能拉伸机等设备,研究了不同热轧温度及退火工艺参数对铝-镁复合界面的显微组织和结合强度的影响.结果表明:300℃轧制,镁-铝复合板出现严重边裂;450℃轧制,边裂消失;在轧制温度为400℃、压下率为50%、300℃退火2 h的条件下得到的复合板界面结合强度最大,为7.5 MPa.
採用AZ31鎂閤金和純鋁進行高溫複閤軋製製備鎂-鋁複閤闆,使其兼具鋁的錶麵耐蝕性和鎂閤金的高比彊度特性.採用金相顯微鏡、掃描電子顯微鏡和電子萬能拉伸機等設備,研究瞭不同熱軋溫度及退火工藝參數對鋁-鎂複閤界麵的顯微組織和結閤彊度的影響.結果錶明:300℃軋製,鎂-鋁複閤闆齣現嚴重邊裂;450℃軋製,邊裂消失;在軋製溫度為400℃、壓下率為50%、300℃退火2 h的條件下得到的複閤闆界麵結閤彊度最大,為7.5 MPa.

Pure aluminum and AZ3 1 magnesium alloy were combined,using high temperature rolling,to make magnesium-aluminum composite plate,which will have a good surface corrosion resistant of aluminum and an excellent specific strength of magnesium. Metallographic microscope,scanning electron microscopy,electronic universal tensile machine and other equipment were used to test the effect of hot rolling temperature and the processing parameters of the annealing on the microstructure and the binding strength of the magnesium-aluminum composite plate.
