In this investigation, Al1060 and pure copper are used to fabricate bi-metal Al–Cu composites via accumulative press bonding (APB) process. The Al and Cu bars were press bonded and continued up to five pressing steps. In the APB technique, the composites manufactured were heated at 320^∘C for about 8min and prior to each forming step. Mechanical properties of these bi-metal composites were assessed in evaluation to Al–Al and Cu–Cu APB processes Metal Matrix Composites (MMCs). It was shown that both Al and Cu deform in the same style in the Al–Cu samples after two steps-APB steps and afterward Cu layers started to neck. Also, it was realized that the average value for the strength of the Al/Cu composites is upper than that of these two MMCs fabricated via one metal. The peeling strength of these products enhanced via the APB steps. Moreover, the effect of APB steps on the fracture and peeling surfaces of bi-metal composites have been investigated by using scanning electron microscopy (SEM).

通过 APB 技术生产的双金属 Al/Cu 块状复合材料的机械和结合性能

在这项研究中，Al1060 和纯铜用于通过累积压接 (APB) 工艺制造双金属 Al-Cu 复合材料。铝条和铜条被压接并持续至多五个压制步骤。在 APB 技术中，制造的复合材料在 320 ^∘ C 下加热约 8分钟和之前的每个成型步骤。这些双金属复合材料的机械性能在评估 Al-Al 和 Cu-Cu APB 工艺金属基复合材料 (MMC) 时进行了评估。结果表明，经过两步 APB 步骤后，Al-Cu 样品中的 Al 和 Cu 都以相同的方式变形，然后 Cu 层开始颈缩。此外，人们意识到 Al/Cu 复合材料的强度平均值高于通过一种金属制造的这两种 MMC 的平均值。这些产品的剥离强度通过 APB 步骤增强。此外，使用扫描电子显微镜（SEM）研究了APB步骤对双金属复合材料断裂和剥离表面的影响。
