Abstract
Low cycle fatigue (LCF) behaviors of cast nickel-base superalloy K52 at different temperatures were investigated, and the fatigue parameters were given by analyzing its cyclic stress strain curves and strain-life curves. Cyclic stress response curves show that the alloy exhibited cyclic hardening and softening behaviors at room temperature and 900 ℃, respectively. OM and SEM observations indicated that LCF cracks initiated predominantly on the...
