Fig.4 Deformation-induced ε→γ transformation in Fe-15Mn and Fe-17Mn damping steels[19] (a) austenitic orientation imaging map (OIM) in 5% deformed Fe-15Mn damping steel (Inset shows the standard inverse pole figure of austenite) (b) EBSD phase map in 5% deformed Fe-15Mn damping steel (Red region denotes austenite, yellow region denotes ε-martensite, green region denotes α'-martensite. TD—transverse direction, RD—rolling direction) (c) TEM image of 5% deformed Fe-17Mn damping steel (Inset shows the SAED pattern of γ phase)
