Abstract Scope Tremendous attention has been devoted recently to near-equiatomic ferrous compounds as rare-earth-free novel magnetic materials. Chemically ordered L1₀ FePt, FePd and FeNi have magnetocrystalline anisotropy constants in the range of 1 x 10⁷ to 6.6 x 10⁷ erg/cc and saturation magnetization values that compare well with those of the current best-in-class rare-earth permanent magnets. In the current study, the effect of plastic deformation on L1₀ chemical ordering in FePd has been studied using differential scanning calorimetry to quantify the transformation kinetics and transmission electron microscopy to characterize the microstructure. The calorimetry and microstructure data are used to propose nucleation and growth mechanisms for the fcc→L1₀ transformation in undeformed and deformed samples. It is shown that the effective energy barrier for the transformation is significantly reduced when the alloy is plastically deformed.
