The autogenous friction welded- titanium alloys, Ti-6Al-4V and Ti-6Al-2Sn-4Zr-6Mo, were studied during this Ph.D. degree. An investigation was conducted on the microstructure evolution, fracture toughness and fatigue crack propagation behaviour of autogenous inertia welded Ti-6Al-2Sn-4Zr-6Mo. The microstructure and fatigue threshold behaviour of linear friction welded Ti-6Al-4V were also assessed in both the as-welded and the post weld heat treated conditions, and the fracture toughness was assessed at room temperature in post weld heat treated condition only. The fatigue threshold behaviour of the autogenous linear friction welded Ti-64 in the as-welded condition was assessed to help understand the edge cracking phenomenon which was observed in the as-welded linear friction welded Ti-6Al-4V BLISK joints.
