EBSD phase map and IPF map of (a1) FSA and (a2) FSA + Anneal specimens in undeformed condition; (b1) engineering strain–stress and (b2) work hardening rate curves of FSA and FSA + Anneal specimens under quasi static tensile testing load; EBSD phase map and IPF map of (c1) FSA and (c2) FSA + Anneal specimens in deformed condition. Note that deformational twins are labelled by black arrows in (c1 and c2). Also note that the red color displayed in phase map of (a1), (a2) and (c1) represent regions with low confidence indexes values rather than ε (HCP) phases.
