Abstract: Elemental Fe and red phosphorus powders with a composition close to Fe-xP (x = 10, 15 and 20 wt. %) were mechanically alloyed in a planetary ball mill under an argon atmosphere. Structural changes were studied by X-ray diffraction. The complete dissolution of the elemental powders is achieved within 3 h of milling. Detailed analysis of the X-ray diffraction patterns reveal the formation of a Fe(P) solid solution with two structures (α-Fe1 and α-Fe2) having different lattice parameters, crystallite size and microstrains in addition to FeP, Fe2P and Fe3P phosphides. The structural parameters and phase percentages are P content dependent.
