“…Therefore, GROD becomes a more sensitive misorientation indicator than KAM. Githinji et al 5) also reached a similar conclusion about the sensitivity of KAM and GROD as a function of the plastic strain. Because GROD evaluates misorientation across a long distance that corresponds to the grain size, the GROD value depends on the grain size.…”

“…In order to verify the role of crystallographic orientations and grain boundary characteristics in IGC resistance, another sample of the same material was solution treated at 1040 °C followed by ageing at 600 °C (1112 °F) for 1 h [35] (as the minimum temperature required to reach the austenite phase). Then, the sample was subjected to hydrogen cathodic charging with a current density of 300 mA/cm 2 .…”

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.
