Abstract
This paper presents the synthesis and mechanical properties study of Magnesium reinforced nano alumina powders with variation in volume percentages of alumina. The magnesium nano alumina composites are developed by reinforcing with 3 amounts of nano alumina (i.e., 0.35, 0.7, and 1.4 volume%) to the magnesium. Monolithic magnesium and its nano composites are synthesized by using the powder metallurgy technique. Samples are produced from nano-composite powders by the cold compacting process done on UTM. Samples are sintered to a temperature of 600-620°C in the presence of the Argon gas flow with a pressure rate of 15L/min. Green density and sintered densities are calculated and compared for all the compositions. It is observed that density increased after the sintering. The micro structural verifications are carried out using X-ray diffraction. Hardness values and SEM micro graphs are compared for various compositions of nano alumina to magnesium. An increase in amount of nano alumina reinforcement led to a progressive increase in micro-hardness of pure (Mg) magnesium. Hence by viewing SEM images it is found alumina to be well dispersed in the Mg metal matrix.
