Description 154-164
Optimum process parameters (temperature, pressure, and time) for diffusion welding of aluminium and copper have been
achieved with better shear strength for application in shaped charges using the Taguchi method. The study involved
characterising the type thickness of intermetallic compounds formed at the faying surfaces using optical microscopy,
scanning electron microscopy and electron probe micro analyser, lap shear strength assessment, microhardness, and X-ray
diffraction. It is confirmed that intermetallic compounds of type Al4Cu(σ), Al2Cu (θ),and AlCu (η1)with traces of Al2Cu3 (δ)
and AlCu4 (α2) were formed at the interface. The optimum shear strength of 42.2 N was achieved with diffusion welding at
temperature 510oC, pressure 0.5MPa and time 5400s.By diffusion welding at these conditions, the shape charge cones
fabricated and explosively filled such shaped charges paved, an increase of 0.42 times in the penetration of target with
diffusion welded copper-aluminium shape charge cones compared with that from conventional monolithic copper sheet.
