Effect of different interlayer on Al 5052/SS 316 explosive cladding

Abstract

The study presents the microstructural and strength characteristics of Al5052/SS316 explosive clads interlaced with different interlayer (aluminium 1100/SS 304/copper) by varying standoff distance (6 and 8 mm), loading ratio, R (mass of explosive/mass of flyer plate: 0.6 and 0.8) and preset angle between flyer and interlayer (6 and 8°), A. The interface microstructure shows the transformation of an uninterrupted melted layer formed in conventional cladding (no interlayer) into a thin or no reaction product clad, when an interlayer is introduced. Similarly, the kinetic energy utilization (1.26 –1.79 MJ/m²) and deformation work (0.76 –1.10 MJ/m²) during explosive cladding increase. The explosive clads having an interlayer exhibit higher mechanical strength than the interlayer less explosive clads and the highest strength (RTS: 263 MPa; Ss: 175 MPa) was witnessed for Al 5052/SS 304/SS316 explosive clads at higher parametric levels.
