中文摘要：在大气环境下采用两种镁铝共晶合金粉末作为中间层(钎料)，分别在460、480 ℃下施加30 MPa压力，制备了AZ31/Al层状复合材料。采用粘接拉伸试验测试了连接件界面的结合强度。 结果表明：镁合金基体与铝基体都与中间层发生了扩散，形成了冶金结合；连接界面呈明显的层状结构，其抗拉强度达24 MPa。
英文摘要：The composite using duplex metal plates with magnesium alloy (AZ31B) as matrix and pure aluminum (1050) as cover layer were manufactured by direct hot pressing under 30 MPa with Mg-Al eutectic alloy as the solder in atmosphere. The results show that a metallurgical bonding between the matrix and the cover layer is achieved by the formation of distinct bonding subzones. The tensile strength of the bonding interface is 24 MPa.
