In this research, Effect of explosive ratio parameter on interface properties of explosively bonded copper-410 martensitic stainless steel were investigated, plates were welded in constant standoff distance with different explosive ratios. Optical microscopy, scanning electron microscopy, Microhardness and Tensile shear tests were carried out. The results showed that wavelength, wave amplitude, and locally melted zones increased by increasing explosive ratio due to more severe plastic deformation in the interface. Hardness was increased in near of the interfaces, Hardness also increased by increasing the explosive ratio in the copper and steel sides. The tensile shear test result showed that fracture occurred on the copper side, no separation occurred from the interface and strength of interface was more than the copper side.
