Magnesium based materials are gaining significant attention in numerous engineering and biomedical sectors due to their high specific mechanical properties, biocompatibility and recyclability. Judicious development of materials is crucial for finding applications in automobile, aerospace and biomedical sector to realize desired properties as well as to help in maintaining the ecological balance with the environment. In search of such lightweight and high performance materials, magnesium nanocomposites containing Sm2O3 rare earth oxide (REO) nanoparticles were developed using powder metallurgy in absence of any protective inert atmosphere. The nanocomposites exhibited an excellent combination of strength, ductility, ignition resistance, and damping behaviour that is attributed to the presence of Sm2O3 nanoparticles. This study opens the door for new series of nanocomposites based on Mg/REO formulations for development of new lightweight high-performance Mg based materials.
