Influence of interfacial defects on the impact toughness of solid state diffusion bonded Ti-6Al-4V alloy based multilayer composites

Microstructure and mechanical properties, with emphasis in impact toughness behaviour, of two multilayer composites have been investigated. The multilayer materials are constituted by thirteen layers of high strength Ti–6 Al–4 V alloy. Stacked layers have been successfully joined by diffusion bondin...
