The stacking fault energies were used to illustrate the footprint of magnetism on the mechanical properties of Fe–Cr–Ni alloys forming the basis of austenitic stainless steels. It was found that the usual chemical effects of alloying additions were accompanied by major magnetic effects, which stabilize the most common industrial alloy steels at normal service temperatures. It was suggested that part of the uncertainties associated with the experimental data on the stacking fault energies were due to the strong concentration and temperature dependence originating from the persisting local magnetic moments.Stacking Fault Energy and Magnetism in Austenitic Stainless Steels.
