a Simulated values of Ms versus the dislocation-generating plastic strain, where data points show the Ms measured for five sets of different dislocation configurations. The average values of Ms are connected by segments to guide to the eye. b Simulated dependence of the volume change on temperature for samples with different plastic deformation. Inset: volume change versus temperature for an elastically isotropic alloy with a volumetric coefficient of thermal expansion of α =24×10−6/K19 (red line), simulated volume change versus temperature for a sample with ~10% plastic strain (blue line), and the sum of both (black line)
