Twinning-related grain boundary engineering
WebTwinning is a key deformation mechanism in face-centered-cubic (fcc)-based and some body-centeredcubic (bcc)-based alloys, which imparts excellent strength-ductility combination by increasing strainhardenability. Typically, twinning in fcc-based alloys increases when the stacking fault energy is lowered via changes in composition. WebGrain boundary engineering of Fe-based austenitic stainless steels and other materials has been successful in producing a large increase in twin and twin related grain boundaries from a wide range of thermomechanical treatments. However, the exact mechanisms and ef
