摘要

以1060铝合金片和AZ31镁合金片为原材料，制备了铝镁微叠层复合材料，研究了层厚比对复合材料组织与性能的影响。使用金相显微镜、X射线衍射仪、场发射电子探针和扫描电镜对复合材料的组织结构、元素分布、裂纹扩展情况进行分析。结果表明，采用真空热压烧结技术制备的复合材料结合良好，力学性能呈先上升后下降的趋势。铝镁层厚比为1∶1.5时复合材料性能最佳，其抗弯强度为159 MPa

比强度为7.4×10~4 N·m/kg

抗压强度为310 MPa。

Abstract

Taking 1060 Al and AZ31 magnesium alloy sheets as raw materials

the effects of layer thickness ratio on microstructure and properties of prepared Al-Mg microlaminated composites were investigated. The microstructure

element distribution and crack propagation of the composites were analyzed by metallographic microscope

X-ray diffractometer

field emission electron probe and scanning electron microscope. The results indicate that the composites prepared by vacuum hot pressing sintering is well-bonded

and the mechanical properties is increased firstly and then decreased. When the thickness ratio of Al-Mg layer is 1∶1.5

the composites exhibit desirable properties

where the bending strength is 159 MPa

the specific strength is 7.4×10~4 N·m/kg

and the compressive strength is 310 MPa.
