Abstract:In this study, the effect of varied loading ratio (mass of the explosive/mass of flyer plate) on the nature of interface, temperature and pressure developed in aluminum-steel explosive cladding is presented. Increase in the loading ratio, R, enhances the pressure developed, kinetic energy utilization and deformation work performed. Interfacial microstructures exhibit the formation of molten layer at few spots, owing to the increase in temperature beyond the melting point of parent alloy. The increase in temperature and the quantum of pressure developed were determined by numerical simulation performed in Ansys AUTODYN by employing smoothed particle hydrodynamics (SPH) method. The positioning of the experimental conditions on the weldability window is presented as well.

 

Key words: explosive cladding; dissimilar metals; numerical simulation; microstructure; weldability window
