ABSTRACT
Strong and lightweight materials are the need of the hour for the weight critical industries such as aerospace and the
automotive sectors. Magnesium with high specific strength is the lightest structural metal available on earth. However, its
industrial application is restricted because of its limited ductility under tensile loads, poor elastic modulus, and low creep
resistance at higher temperatures. This study aims to investigate the effect of yttrium and yttrium oxide nanoparticles on the
mechanical response of pure magnesium. Magnesium-yttrium binary alloy and its nanocomposite with yttrium oxide as
reinforcement were casted using disintegrated melt deposition technique at 750oC followed by hot extrusion. The binary alloy
and nanocomposite were subsequently characterized for their microstructural and mechanical properties and were compared
with pure magnesium. The mechanical behavior tested in compression demonstrated progressive increase in strength after
addition of yttrium and yttrium oxide. On contemplation, relationship between microstructure of the engineered composite and
mechanical properties was established.
