摘要

铝和镁合金是具有突出技术用途的轻质材料。由于铝和镁合金的综合性能,它们的复合材料已经超过了单独使用这些元素。采用累积辊焊技术制备了铝合金/镁合金/铝合金三层夹心复合材料结构。研究了复合材料的显微组织和力学性能。显微组织研究表明,形成了细晶AZ31层。在铝合金/镁合金接触处,也观察到扩散层。在断裂面上,断口形貌同时表现出韧性和脆性破坏特征。

Sandwich composite of aluminum alloy and magnesium alloy through accumulative roll bonding technique
Aluminum and magnesium alloys are lightweight materials with outstanding technical uses. Due to their combined qualities, composites built of aluminum and magnesium alloys have surpassed the utilization of these elements individually. Accumulative Roll Bonding was used to create a three-layered sandwich composite structure made of Al-alloy/Mg-alloy/Al-alloy. The composite structure's microstructure and mechanical characteristics were studied. A fine-grained AZ31 layer was formed, according to the microstructural study. At the Al-alloy/Mg-alloy contact, a diffusion layer was also seen. On the broken surface, fractography exhibited both ductile and brittle failure characteristics.
