چکیده

In the present study, the fabrication of tri-layer composites by explosive welding and subsequent rolling has been investigated. The effect of cladding/deformation variables on the integrity, the soundness and microstructural properties were evaluated using optical microscopy as well as the micro-hardness testing. It was observed that, when the explosive ratio was increased smooth bonding interface transformed to a wavy interface accompanied by the formation of intermetallic components. The hardness of bonding interface of plates was increased because of deformation that was originating from the impact effect. Interest was directed towards the surface topography, metallurgical changes of interface zone and characterization of defects could affect the properties of the composite products. In addition, the difference in the plastic strain experienced by each material increases with increase in the total plastic strain and volume ratio that may result in de cohesion, fracture or other heterogeneity.
