Abstract:
      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.
