Abstract
Ratcheting experiments were carried out on 316LN stainless steel as a function of temperature ranging from 523 -923 K for different mean stress (σm)-stress amplitude (σa) combinations. The effect of temperature on ratcheting strain accumulation as well as cyclic life is found to be anomalous due to occurrence of Dynamic Strain Aging (DSA). While the peak DSA temperature is at 823 K for all mean stress-stress amplitude combinations, the temperature regime in which DSA operates varied for different σm - σa combinations.
