Abstract
In this article, Incoloy800 and SS304 (304 stainless steel) were cladded by explosive welding. Accordingly, micro-hardness, tensile strength, shearing strength, bending properties, and SEM microstructure of cladding plate were examined in detail. The bonding interface of the plate showed a wavy morphology. Whereas, a different colorful area was observed at the wave ridge of the base layer either in optical or SEM pictures. Magnetic inspection showed that the colorful area was austenitic steel. Thus, the occurrence of the colorful areas seemed to be the result from the high deformation/cold working of the grains. EDX spectrum analysis and line scanning indicated that the diffusion through the bonding interface was not observed under the EDX and line scanning detection limitation. Micro-hardness, tensile, shearing, and bending testing results showed that the bonding strength was acceptable according to ASTM specification.
