Fig.2 ε-martensitic transformation mechanism in Fe-17Mn-0.3Si damping steel after 24% warm deformation[14] (a) Schmid factor map of austenite (G1—original autenite grain 1, G2—original autenite grain 2) (b) local disorientation map of austenite (c) austenitic φ2 = 45° orientation distribution function (ODF) section for circular region in G1 (φ1, φ2, ϕ—Euler angles) (d) schematic of intersection of (111) γ plane and (001) γ plane (yellow line) (e) intersections of {111} γ planes and (001) γ plane (The solid lines P1/149° and P3/31° represent the intersection lines that {111} γ planes have a large Schmid factor, the angles between the two lines and rolling direction are 149° and 31°, respectively. The dashed lines P2/59° and P4/121° represent the intersection lines that {111} γ planes have a small Schmid factor, the angles between the two lines and tensile deformation direction are 59° and 121°, respectively)
