Synthesis Of Fe-C Alloys By Mechanical Alloying
Fe-C alloys; Mechanical alloying; Scanning electron microscopy; X-ray diffraction
We present here our results on the synthesis of iron-carbon alloys (steel and cementite) starting from blended elemental iron and carbon powders. The powder particle size decreased and the lattice strain increased with increasing milling time, as determined from the width of the X-ray diffraction peaks and also confirmed by scanning electron microscopy. On the milling of the powder for 10 h, new X-ray diffraction peaks started appearing, and these became prominent with continued milling. Formation of the Fe-C solid solution phase with a BCC structure and the cementite phase were noted when the amount of carbon was small (Fe-0.8 wt % C), as indicated by a shift in the iron powder diffraction peaks and new peaks. On the other hand, a homogeneous cementite phase had formed at the higher carbon contents Fe-7 wt % C). The microstructural evolution of the milled powder was also studied as a function of milling time. The milled powders were consolidated to full density by spark plasma sintering and the microstructure and mechanical properties of the compacts are being investigated.
