Fig.4 EBSD images of the 3Mn-0.2C MMS at ε = 0.22 (a), 0.51 (b), and 0.92 (c) with the hot deformation under T = 660^oC and $\dot{ε}$ = 0.001 s^-1 (The yellow arrows in Fig.4b indicate the ferrite grains formed along the intragranular deformation bands. The green and blue lines in the figures represent boundaries with 2° ≤ θ < 15° and θ ≥ 15°, respectively)
