Abstract
The present work pertains to the study of microstructure and mechanical properties of explosively clad high strength low alloy steel with commercially pure titanium. The clad interface was characterized by metallography, hardness, shear bond strength and bend tests. The present study revealed that the clad interface was wavy in nature. Shear bond strength of clad interface was in between substrate and clad material. The three point bend tests were conducted on clad joint in such a way that cladding layer was subjected to tension and compression which have not shown any cracks at the interface. The mechanism and reasons for the observed behaviour have been discussed correlating microstructure, mechanical properties, fracture features and diffusion across the interface.
