Abstract
The purpose of this investigation is to examine the evolution of phase formation, structural, microstructural, and magnetic properties of the Fe50Cr40P10 (wt.%) powder mixture as a function of milling time. The Rietveld refinements of X-ray diffraction patterns indicated the formation of two bcc chromium solid solutions, Fe33Cr2 and Fe2Cr5, embedded within α-Fe (P) solid solution. The magnetic measurements reveal a ferromagnetic behavior regardless of milling time, but highlight a new behavior of phosphorus as an alphagen element to promote the alpha iron chromium solid solution formation with lower hysteresis loss energy and maximum values of the magnetic properties (coercivity, Hc, nucleation field, Hn, initial µi and maximum µmax magnetizations permeabilities as well as the hysteresis loss energy EHL). The evolution of magnetic fields has been correlated with the evolution of <L>, rms <σ2>1/2, and dislocation density ρ.
