K IA is increasingly being regarded as a characteristic fracture toughness below which cleavage fracture does not occur. Its evaluation from small-sized Charpy specimens would be advantageous for applications in power plant industries. In this study, K IA has been evaluated for P91 steel in various cold worked and thermally aged conditions. Evaluation of K IA requires determination of crack arrest load(P arrest) and crack arrest length(a arrest). The main challenge is in the determination of a arrest due to the non-availability of standard methodologies and the absence of unequivocal microstructural signatures on the fracture surface in this steel to identify crack arrest. a arrest has been determined using the analytical Key-Curve methodology which has proven successful for this steel in unaged condition. The applicability of the Key-Curve method is validated by the good agreement of the determined final crack length with that measured optically on unbroken specimens of N&T and subsequently 15% cold-worked P91 steel which had been previously aged at 650?°C for 5000?h. Mean K IA varies from 47.46?MPa√m (NT steel aged at 600?°C for 5000?h) to 69.85?MPa√m(NT?+?15% cw steel aged at 650?°C for 10000?h) for the various cold worked and aged datasets. K IA is found to be an average property unlike initiation toughness (K Jd) which shows statistical scatter. Mean K IA is found to be in reasonable agreement with the lower bound values of cleavage initiation toughness (K Jd) for the datasets in this study.
