- The origins of the Bauschinger effect (a change in the stress/strain characteristics of a material) are widely debated. This work, funded by EDF Energy, describes novel interrupted cyclic stress-strain tests to monitor the evolution of grain-scale strains associated with macroscopic deformation in austenitic stainless steel. The results imply that the residual lattice strains generated are the primary source of the Bauschinger kinematic hardening effect observed in austenitic stainless steel. This is significant because this type of material widely used in many industries and understanding how it responds to deformation is important for estimation of the lifetime of metallic components.
