Abstract The abnormal segregation of Mn along grain boundaries in an austenitic steel containing 26％ Mn was identified by both Auger energy spectrum and ion microprobe analysis. The morphology of its high temperature fractogrph is shown as brittle intergranular fracture instead of normal ductile dimple.
