- Abstract
- In spite of the formation of a high fraction of deformation-induced alpha' martensite, the tensile elongation of a cast high-nitrogen austenitic stainless steel was found to enhance at lower temperatures, a behavior deviating from that exhibited by wrought and homogenized austenitic stainless steels. The observed behavior was explained by the presence of microstructural regions with different stabilities with respect to deformation-induced alpha' martensite formation caused by the segregation of alloying elements.
