Variant selection during mechanically induced martensitic transformation of metastable austenite by nanoindentation

Multiple pop-in events which indicate a gradual transformation from a metastable austenite grain to martensites in steel were detected during nanoindentation. It was observed by means of an automotive mapping technique with TEM that the partial volume of prior austenite had transformed into several...
