“…Following that, several studies characterized the variation in phase fractions of bending samples (e.g., Refs. [6,12,13]), whereas Ogawa et al [ 14 ] and He et al [ 15 ] investigated the effects of alloying elements on the variations in phase fractions. More recently, some of the present co‐authors studied microstructure and microtexture evolution, [ 16 ] the orientation dependence of deformation‐induced martensitic transformation, [ 7 ] and the effects of strain rate on the microstructure and microtexture evolution [ 17 ] in a TRIP–TWIP steel during bending.…”

Microstructure evolution via deformation-induced martensitic transformation, void formation, and crack propagation is investigated in a metastable austenitic Cr-Mn-N stainless steel for up to 90°bending using a combination of electron backscattering diffraction and parent grain reconstruction. Stress-strain heterogeneity and stress triaxiality studied using finite-element analysis reveal that the inner and outer radii are in approximately uniaxial compressive and tensile stress states, respectively, with the outer radius showing higher values for von Mises and principal stresses and equivalent strain. Voids are observed at both austenite/α 0 -martensite and α 0 /α 0 -martensite interfaces. Parent grain reconstruction applied to the 90°bending sample reveal that the cracks at α 0 /α 0martensite interfaces tend to propagate predominantly along intergranular parent austenite grain boundaries. It is also found that both intragranular and intergranular cracks in parent austenite tend to propagate between α 0 -martensite child-child grains comprising the same crystallographic packets. This is the first study of its kind to comprehensively show this phenomenon. A representative example of intergranular crack propagation within a 110 h i‖normal direction (ND)-oriented parent austenite grain is also demonstrated.

“…Very few studies of the large amplitude cyclic and non-proportional response of metastable austenitic stainless steel are available in the literature. Van Beeck et al [37] show results of bending-unbending experiments of austenitic stainless steel plate. During the unbending stage a pronounced non-linear effect is observed, which is not present in a nontransforming steel.…”
