Abstract
Abstract In this paper, Incoloy800 and 304 stainless steel (SS304) were clad by explosive welding. Accordingly, hardness, tensile strength, shearing strength, bending properties and microstructure of the clad plates were evaluated. The bonding interface showed a wavy morphology. Line scanning results indicated that there was no diffusion area through the bonding interface. Whereas, a colorful zone was observed at the wave ridge of the base metal (white area in optical microscopy and black area in scanning electronic microscopy). Energy dispersive spectroscopy analysis indicated that compositions and contents of the colorful zone were the same as that in the base metal. Hardness testing showed that the highest value of hardness was obtained in the colorful zone. Thus, the colorful zone was an intensive deformation area in SS304, which was produced by shock pressure from collision. Mechanical tests showed that the clad plate was acceptable according to ASTM specification.
