Formation and Decomposition of Cementite in Mechanically Alloyed Iron-Amorphous Fe-C Phase Nanocomposite upon Heating and Isothermal Annealing at 700 deg C

摘要

X-ray diffraction analysis, Mossbauer spectroscopy, atomic force microscopy, and magnetic measurements were used to study structural and phase transformations in a mechanically alloyed Fe-C nanocom-posite containing 15 at. percent (3.7 wt percent) C upon heating to 700 deg C and holding at this temperature for 10 h.
