In the present study, a multilayer Al/Cu composite reinforced with AISI 304 stainless steel wires was fabricated through an accumulative roll bonding process. The microstructure and bonding integrity of different layers were investigated using optical and scanning electron microscopy. Mechanical properties of the produced composite samples were evaluated by tensile testing and micro-hardness measurements. Results showed that after six cycles of ARB processing, a multilayer Al/Cu composite with uniform distribution of Cu and AISI304 wires in an Al matrix is produced. Also, the results of tensile testing indicate that both the strength and elongation of the fabricated composite decrease with increasing the ARB cycle. Scanning electron microscopy analysis of the fractured surfaces of tensile specimens showed a combination of ductile rupture with deep dimple forming and cleavage fracture at different composite layers.

在本研究中，通过累积辊压粘合工艺制造了用AISI 304不锈钢丝增强的多层Al / Cu复合材料。使用光学和扫描电子显微镜研究了不同层的微观结构和结合完整性。通过拉伸试验和显微硬度测量来评估所生产的复合材料样品的机械性能。结果表明，经过6个循环的ARB处理后，生产出的多层Al / Cu复合材料具有均匀分布的Cu和AISI304丝在Al基体中。而且，拉伸试验的结果表明，所制造的复合材料的强度和伸长率都随着ARB循环的增加而降低。
