Abstract

Hybrid nano reinforcement particles with increasing volume percentage of copper have significantly enhanced tensile properties of commercially pure magnesium when incorporated using blend-press-microwave sintering powder metallurgy process. Incorporated hybrid reinforcement maintained their strengthening effect on magnesium matrix up to the temperature limit used in this study although gradually declined with increasing test temperature. Reinforcement particle assisted dynamic recrystallisation and thermally activated deformation process induced near super plasticity in commercially pure magnesium matrix at incomparably lower temperature and suggested the potential of near net shape fabrication in to intricate shape. Limit in total volume fraction of nanometre size reinforcement resulted the hybrid nano reinforcement with 0.3 vol.-% of metal particle most effective to enhance tensile characteristics of commercially pure magnesium.
