Abstract

We report evidence of displacive phase transformation from retained austenite to martensite during preparation of quenched and partitioned steel micro-pillars by using focused ion beam (FIB) technique. The BCC phase produced by the FIB damage was identified as martensite. The invariant- plane strain surface relief associated with the martensitic transformation was observed in the retained austenite phase immediately after a FIB scan of the surface with the Ga+ ion beam. This report addresses challenges related to the preparation of austenite micro-pillar by conventional FIB technique.
