采用铸造+轧制制备了1060Al/AZ31Mg层状复合材料,研究了铸造1060Al/AZ31Mg层状复合材料界面结构及性能,并研究了轧制对复合材料组织的影响。结果表明,铸造1060Al/AZ31Mg层状复合材料界面生成了金属间化合物,从1060Al侧向AZ31Mg侧依次为Al Mg化合物层、Mg17Al12化合物层、Mg+Mg17Al12共晶层。界面金属间化合物层显微硬度明显高于两侧母材,靠近1060铝合金侧化合物层达到最大值250 HV左右。1060Al/AZ31Mg层状复合材料轧制后界面金属间化合物破碎,累计压下量80%时,金属间化合物基本消失。
The 1060Al / AZ31Mg layered composites were prepared by casting and rolling. The interfacial structure and properties of 1060Al / AZ31Mg layered composites were investigated. The effects of rolling on the microstructures of composites were investigated. The results show that the intermetallic compounds are formed at the interface of 1060Al / AZ31Mg layered composites, which are Al Mg compound layer, Mg17Al12 compound layer and Mg + Mg17Al12 eutectic layer from the side of 1060Al1 to AZ31Mg. The microhardness of the interface intermetallic compound layer is obviously higher than that of the two base metal materials, and the compound layer near the 1060 aluminum alloy reaches a maximum of about 250 HV. The intermetallics intermetallics crushed after the 1060Al / AZ31Mg layered composites rolled. When the cumulative reduction of 80%, the intermetallic compounds disappeared.
