They argue that, when the volume of α0-martensite phase is small, it has a strong shape magnetic anisotropy and, consequently, its coercive force is large [6]. Therefore, when the coalescence of the martensite phase occurs (with further deformation), such magnetic anisotropy decreases, as well as Hc [6]. Back to the Fig. 5(a), in light of Ref. [6] we can infer that, up to 20% thickness reduction, the size of the SIM laths is quite small, so that α0-martensite phase has a strong shape magnetic anisotropy. With further deformation, coalescence of the martensite occurs, leading to a decrease of Hc. From Fig. 5(a) note that the highest increase percentage of Ms occurs between 20% and 40% thickness reduction. The strongest reduction of Hc occurs at the same deformation range, as depicted in the same figure. Back to Fig. 3, also for this specific deformation range, a slight decrease in the slope of hardness curve is observed. As previously discussed, such slight decrease in the slope of hardness is due to SIM transformation.
