Influence of varying nitrogen on creep deformation behaviour of 316LN austenitic stainless steel in the framework of the state-variable approach

Primary and steady-state creep deformation of 316LN stainless steel with four different nitrogen weight percent (0.07, 0.11, 0.14, and 0.22% N) have been examined in the framework of internal stress based kinetic creep law. The interrelationship between activation area or activation volume and effective stress has been employed in the present model, rather than the applied stress dependency on these thermodynamic quantities. The model predicted...
