选取Mg-8.5Al-0.5Zn-0.2Mn合金、ZAlSi12合金和中间隔板1060合金为原料,采用铸造成型的方法制备出了Mg/Al层状复合材料,研究了中间隔板厚度对复合材料组织和力学性能的影响。结果表明,复合材料中Mg-8.5Al-0.5Zn-0.2Mn合金、ZAlSi12合金和中间1060合金层结合紧密、在界面处无明显缝隙或者孔洞存在;在过渡层与Mg-8.5Al-0.5Zn-0.2Mn合金和ZAlSi12合金界面处都存在一定的硬度梯度,且中间过渡层硬度都要低于Mg-8.5Al-0.5Zn-0.2Mn合金和ZAlSi12合金母材;中间隔板厚度对Mg/Al复合材料的强度影响较小,而断后伸长率随着中间隔板厚度的增加而逐渐降低。
Select Mg-8.5Al-0.5Zn-0.2Mn alloy, ZAlSi12 alloy and the intermediate plate 1060 alloy as raw material, casting method was used to prepare the Mg / Al layered composite material, the effect of the thickness of the intermediate partition on the composite structure And mechanical properties. The results show that the Mg-8.5Al-0.5Zn-0.2Mn alloy, the ZAlSi12 alloy and the middle 1060 alloy layer in the composite material are tightly combined, and there is no obvious gap or hole in the interface; in the transition layer and Mg-8.5Al-0.5Zn- 0.2Mn alloy and ZAlSi12 alloy interface there is a certain degree of hardness gradient, and the intermediate layer hardness are lower than the Mg-8.5Al-0.5Zn-0.2Mn alloy and the ZAlSi12 alloy base metal; the thickness of the intermediate partition Mg / Al composite The strength of the material has less effect, while the elongation after fracture decreases with the increase of the thickness of the middle partition.
