中文摘要:
      在异步速比为1.7的异步轧制工艺下冷轧制备Cu/Al-Si复合板,不同Si含量的Cu/Al-Si复合板在400℃退火30min后界面获得均匀厚度的金属间化合物。利用OM、SEM、EPMA、XRD、拉伸机等设备分析发现:复合板金属间化合物的厚度在Si含量为8.66%时最大;随着Si含量的增加,复合板的抗拉强度增大,延伸率、剥离强度减小,在Si含量为4.84%时综合性能最好,抗拉强度和延伸率分别为188.63MPa、39.1%;Cu侧的拉伸断口形貌主要呈山脊状,Al-Si合金侧中心区域出现韧窝,韧窝数量随Si含量增加而增加。

英文摘要:
      Cu/Al-Si alloy clads were cold roll bonded with a mismatch speed ratio of 1.7 at ambient temperature, and uniform intermetallic compounds(IMCs) formed when these Cu/Al-Si alloy laminates with different silicon content were annealed at 400 ℃ for 30 minutes. With the utilizition of OM, SEM, EPMA, XRD, tensile machine and so on, it showed that the width of IMCs reached the maximum at 8.66%(wt.%) silicon content. With increase of silicon in Al-Si alloy, the tensile strength of laminated composites increased while elongation and peeling strength of composites went down, and their comprehensive properties reached the best at 4.84% with tensile strength and elongation of 188.63 MPa、39.1%, respectively. Meanwhile, fracture morphology of Cu/Al-Si alloy laminates in Cu side was ridge-like, and structure of Al-Si alloy in center region was mainly dimples, the more silicon content in Al-Si alloy, the more dimples appealed.
