Table S1: Theoretical angle/axis pairs for KS/KS, NW/NW, KS/NW [39] and GT/GT misorientation relationships. Some rotation axes having irrational indexes, they were approximated by low index crystallographic axes. The offset angle between the actual axes and the low-index axes is specified.

Figure S1: (a) and (c) misorientation angle distributions for FeCMn and FeCMoMn compositions with a minimum at 5° and a minimum at 45° (b and d). Misorientation angles with a value inferior to the minimum are disregarded for the frequency calculation. (color necessary for print).

Figure S2: EBSD on the martensitic domain: misorientation axis distributions for the FeCMo composition (a) and FeCMn composition (b). (color necessary for print).

Figure S3: Study in a prior austenite grain for FeCMoMn 1°C/s: (a) EBSD map with a prior austenite grain (PAG) in red, (b) {100}, {110} and {111} pole figures of the PAG (stereographic projection), (c) map of the misorientation angles in the PAG with a profile in white, (d) misorientation profile in PAG. (color necessary for print).

Figure S4: EBSD for the slowest cooling speeds: misorientation axis distribution for the FeCMo composition (a) and FeCMn composition (b). (color necessary for print).

Figure S5: Study in a prior austenite grain for FeCMoMn 0.1°C/s: (a) EBSD map with a prior austenite grain (PAG) in red, (b) {100}, {110} and {111} pole figures of the PAG (stereographic projection), (c) map of the misorientation angles in the PAG with a profile in white, (d) misorientation profile in PAG. (color necessary for print).
