Creep Deformation and Rupture Behaviour of P92 Steel at 923 K
Procedia Engineering, 2013 AbstractCreep deformation and rupture behaviour of P92 steel has been examined at 923K for stresses ranging from 75 to 150MPa. The steel exhibited well defined primary, secondary characterized by minimum creep rate and prolonged tertiary creep stages.
