Modification of the Gurney Equation for Explosive Bonding by Slanted Elevation Angle
2014
Abstract : Using a modified Gurney equation, explosive bonding has been achieved with an angle of elevation between two plates and utilising an explosive charge with supersonic detonation velocity. Two joint combinations were produced with superaustenitic steel as the flyer plate and either TRansformation Induced Plasticity (TRIP) steel or HARD steel as alternatives for use as bottom plates. Good metallurgical bonds were created for each joint combination, with the formation of wave-type microstructural morphology at the joint interface. As a result of localised severe plastic deformation and subsequent work-hardening within the steels the microstructures at the joint interface revealed complex metallurgical phenomena, which correlated strongly with hardness evolution.
