dc.description.abstractIn the present study, magnesium nanocomposites were fabricated by using magnesium as matrix and nano-yttria as reinforcement. Composites with 0.5 and 2.0 wt.% of Y2O3 were synthesized through powder metallurgy route incorporating microwave assisted rapid sintering technique followed by hot extrusion. Microstructural characterization revealed reasonably uniform distribution of Y2O3 particulates in the matrix and the presence of nanopores. Thermomechanical analysis revealed significant reduction in CTE of magnesium as a result of presence of yttria nanoparticulates. Mechanical characterization studies revealed that hardness, 0.2% yield strength, ultimate tensile strength, work of fracture and ductility increased with increasing amount of reinforcement from 0.5 to 2.0 wt.%. The studies revealed that the best combination of mechanical properties is realized from the composite containing 2.0 wt.% of yttria. © 2007 Elsevier Ltd. All rights reserved.
