Abstract

Magnesium nano composites reinforced with 0.5, 1 and 2 wt.% of nano Fe2 O3 particles were blended-hot pressed-microwave sintered powder metallurgy technique. The morphological characterisations of Mg and nano Fe2 O3 were performed using scanning and transmission electron microscopy respectively. The elemental characterisations of powder particles were done using energy dispersive spectroscopy analysis. Physical properties such as density and porosity were calculated as per ASTM standards. The microwave sintered samples were studied in terms of its micro hardness. The fabricated nanocomposites have been characterised structurally by optical microscope. The hardness of the nano composites was significantly increased, to increase the nano Fe2 O3, and also the results establish that the study signify that the proposed method is an effective energy saving for preparing the nanocomposites with extremely denser and enhanced micro hardness, highly homogeneous and uncontaminated microstructure.
