Effect of thermal treatment on mechanically deformed cobalt powder

Stabilization of the FCC phase was obtained after sintering the mechanically milled Co powder at 1400C. The Co powder retained its HCP crystal structure after MM. Phase identification on the milled and sintered Co powders was performed by the X-ray diffraction analysis, while morphology and microstructures were performed using both optical and scanning electron microscopy. Phase transformation traced by the differential scanning calorimetry.
