摘      要：Cu/Al multilayers were produced by high-temperature accumulative roll bonding(ARB)methods up to three *** achieve a high bonding strength,prior to ARB processing,the Cu and Al sheets were heated to 350,400,450 and 500 ℃,*** mechanical properties were evaluated by tensile *** microstructure was examined by optical microscopy and scanning electron microscopy equipped with energy dispersive *** ultimate tensile stress,the grain size and the thickness of diffusion layer of lamellar composites increase with rolling *** the rolling temperature is 400 ℃,the laminates show the highest ductility,but the yield stress is the *** the rolling temperature further increases,both the yield stress and the ultimate tensile stress increase and the ductility decreases *** mechanical properties of lamellar composites processed by low and high temperature ARB are determined by grain size and the thickness of diffusion layer,respectively.
