Consolidation of mechanically alloyed Fe-27 at%Al at high pressure

Abstract:

In the present work consolidation of nanocrystalline mechanically alloyed powders of Fe-27at% Al supersaturated solid solution after different milling times, were carried out under different hydrostatic pressures. A study of the effect of pressure and temperature on the material consolidation is presented. Higher densification is obtained for the highest pressure and sintering temperature. It was found that the combination of high pressure and high temperature (2 GPa-600°C) results in a more homogeneous microstructure with smaller grain size.
