The bonding layers in dissimilar alloy explosive bonding joints,γ/α stainless steels, copper/carbon steel and brass/γ-stainless steel have been studied by means of TEM tech- nique.The results show that the bonding is obtained by diffusion and local melting at the con- tact surface.The structure of bonding layer not only responds to the compositions of the bond- ing alloys,but also the difference between their thermal conductivities,melting points and recrystallization temperatures,Because of the small molten region and fast cooling rate,the structure of molten region could be amorphous or microcrystals,and both stable and metastable phases exsist.
