摘要: The present study reports the development of Mg–Sm2O3 nanocomposites as light-weight materials for weight critical applications targeted to reduce CO2 emissions, particularly in transportation sector. Mg-0.5, 1.0, and 1.5 vol % Sm2O3 are synthesized using a powder metallurgy method incorporating hybrid microwave sintering hot extrusion. microstructural studies showed dispersed nanoparticles (NPs), refinement grain size due presence NPs, limited porosity. Microhardness dimensional stability pure Mg increased with progressive addition NPs. NPs matrix enhanced ignition temperature by ~69 °C. ability absorb vibration also progressively room compressive strengths (CYS UCS) were found be higher without having any adverse effect on ductility, leading significant increase energy absorbed prior failure. Further, characteristics correlated enhancement various properties exhibited nanocomposites.
