Evolution of irradiation-induced strain in an equiatomic NiFe alloy

FIG: (a) Accumulation of point defects in the NiFe alloy with increasing number of cumulative recoils. (b) Change of volumetric strain (εvol = εxx + εyy + εzz) as a function of number of recoils. The strain values are averaged over the total number of strained atoms in the system. The corresponding dose in displacements per atom (dpa) is also given in both plots.247
