Abstract:A continuous solid/liquid bonding method was successfully developed to fabricate Cu-10wt-%Ni-1wt-%Fe (nickel bronze) clad steel with a good metallurgical bonding in the present study. The results indicated that the diffusion distance of interface is about 1.90-2.18 mu m. The average tensile shear strength of centre composite strip at as-cast state is 228 +/- 5 MPa, while that of edge is 202 +/- 6 MPa, and the interface strength is higher than that of bronze since the fracture always occurs on the nickel bronze side. After the rolling process, the tensile shear strength increases with the increasing rolling reduction. The reason can be ascribed to the strengthening of the nickel bronze whose strength is still lower than the interface.
