Elevated temperature crack growth in inertially welded nickel-based superalloys and gamma based titanium aluminides

An evaluation of inertia friction welds in RR1000 has been conducted through microtensile and sustained load crack growth tests on pre-cracked testpieces. As-welded and two post weld heat treatment conditions have been considered. The fatigue crack growth behaviour of γ TiAl has also been considered, with a focus on establishing fatigue crack growth thresholds.
