Analysis of shot-peening and residual stress relaxation in the nickel-based superalloy RR1000
Knowing residual stress evolution in RR1000 is vital for robust lifing and is reported for the first time in this paper. Surfaces/surface stresses play vital roles in aeroenigne disc integrity where fatigue limits life and can lead to catastrophic failure (Quantas 2010). This paper results from a Rolls-Royce iCASE* which includes internationally-recognised research on interaction of oxygen with fatigue cracks, leading to EPSRC PI grant ‘Oxidation Damage at Crack Tips and Its Significance in Crack Growth under Fatigue-Oxidation’ (EP/K027344/1 £341,940 Jan13), a fully-funded PhD student (Malaysian Government), a further RR CASE award and unsolicited invitation to collaborate (Erlangen University). *Mark.hardy@rolls-royce.com
