Tebib, Wassila Alleg, Safia Grenèche, Jean-Marc Suñol, Juan Jose Thermal stability of the nanocrystalline Fe-8P (wt.%) powder produced by ball milling <p></p> <p>The thermal stability of Fe-8P (wt.%) ball milled powders was investigated by differential scanning calorimetry X-ray diffraction and <sup>57</sup>Fe Mössbauer spectrometry. The effect of structural disorder is evidenced in the DSC thermogram by the presence of a large exothermic reaction consists of several overlapping peaks and spread over the temperature range (150-700)°C. The result of the Rietveld refinement of the XRD patterns indicates that during the annealing of the powders up to 210°C, three phases are observed: α-Fe(P), solid solution Fe<sub>3</sub>P and FeP phosphides. The Mössbauer spectra analyses show that the paramagnetic FeP phosphide phase is the only product after the annealing (∼ 2%). The annealing at 450°C leads to a mixture of α-Fe(P) solid solution, Fe3P nanophase and a small amount of a paramagnetic FexP (1 < x < 2) phosphide phase (∼ 3%) in addition to iron oxides.</p> Fe-P alloys;ball milling;annealing;DSC;rietveld;mössbauer 2018-07-12
