- Grain boundary serrations were produced in heat-resistant austenitic stainless steel
containing Cu by applying after solution heat-treatment a holding time in the range 700-800℃
between 30 minutes to 3 hours. These special treatments provide an enhancement of the tensile
ductility of about 40 and 113%at room temperature and 750℃, respectively, while no significant
change in the yield stress and tensile strength could be observed.
