A vacuum roll bonding apparatus has been developed to produce clad metals. Clad metals such as Al/SS41,A5083/SS41,Cu/SS41,Ti/SS41,SUS304/SS41,Al/Cu, Al/Ti, Cu/Ni, Cu/Ti and Nb/Ti were produced at temperature in the range 0.7-0.85 of the homologous melting temperature using the vacuum roll bonding. And bond mechanism on this method, bond microstructure and bond strength of the clad metals have been investigated. The results obtained are as follows ;(1) Bondings of dissimilar metals such as aluminum clad steel, which is difficult to bond by diffusion bonding, were performed under the low reduction in thickness.(2) Though the bondings were performed at elevated temperature, interdiffusion of the elements at the bond interface which occurred during the bonding and cooling process was so little that it was not detected by EPMA analysis.(3) Bond shear strength of A5083/SS41,SUS304/SS41 and Ti/SS41 was higher than that specified by JIS. As the bond shear strength of other clad metals was very high, shear fracture at the bond interfaces did not develop on the shear test.
