Figure 5

SEM/EBSD analysis of 304L specimen C−196°C sliced perpendicular to the cold-extrusion direction and showing the microstructural changes for a cumulative true strain of ε ~ 0.40–0.46. (a) EBSD band-contrast image reveals slip plains forming due to plastic deformation, (b) EBSD phase-analysis image (blue for martensite, red for austenite, white for non-indexing patterns). Inset (a) shows EBSD image (detail from Fig. 1) of the austenite and martensite phases of the laser-surface-treated C−196°C, band-contrast image, while (b) shows a phase-analysis image (red for martensite and blue for austenite) ref. 1.
