Using hierarchical composite approach to improve mechanical response of Mg and Mg-Bi2O3 nano-composites

► Mg grain size refinement owing to presence of Bi2O3 nano-particles. ► Hybridizing agent improves the grain refinement efficiency. ► Trivial textural evolution due to presence of Bi2O3 nano-particles. ► Trivial textural evolution due to presence of hybridizing agent. ► Hybridizing agent improves the mechanical response, further.
