Structural evolution of Fe + Fe2O3 during mechanical milling. Journal of Magnetism and Magnetic Materials 177-181 (PART 2) : 933-934. ScholarBank@NUS Repository.03048853https://scholarbank.nus.edu.sg/handle/10635/107205The evolution of structure during the mechanical milling of the Fe + Fe2O3 mixture has been studied. Magnetite, Fe3O4, was initially formed after milling for short times. Nearly single-phase wüstite, FeO, was found after milling for 30 h or longer. The kinetics of the phase transformations was studied by X-ray diffraction, Mössbauer spectroscopy and magnetic measurement. Nanocrystalline wüstite formed during mechanical milling, decomposed into nanocrystalline Fe3O4 and Fe after annealing at 200-500°C. Annealing at higher temperatures resulted in reformation of the wüstite phase. © 1998 Elsevier Science B.V.
