This research work aims to investigate the mechanically alloyed Fe₁₅Co₂P₃. Parametric Rietveld refinement method, of the obtained X-ray patterns, was performed for qualitative and quantitative phase analysis, structural, microstructural and mechanical properties. The ball-milled powder mixture crystallized within the face-centred cubic α-Fe(P) solid solution in equilibrium with Co₇₅Fe₂₅ phase. The crystallite size decreases reaching 100 and 200 nm respectively after 3h of milling. The highest values of the dislocation density, microstain and stored energy are registered for the α-Fe(P) solid solution. The studied mechanical properties manifest the brittle nature of the α-Fe(P) solid solution compared to the Co₇₅Fe₂₅ phase. The squareness ratio M_r/M_s and the coercivity values of the milled powders increase with increasing milling time and reach steady state after 2 h. The hysteresis loss energy and maximum permeability reach minimal values of 45*10^− 4 W/m³ and 49*10^− 3 H/m respectively, after 1 h of milling at the opposite of the switching field distribution.
