Synergetic effect of GNPs and MgOs on the mechanical properties of Mg–Sr–Ca alloy

Novel Mg composite was fabricated to explore the synergetic effect of GNPs and MgOs on the microstructure evaluation, deformation behavior and mechanical properties of Mg–Sr–Ca alloy. The addition of hybrid reinforcement into the Mg–Sr–Ca alloy led to considerable grain refinement (~53%). The GNPs w...

Zusammenfassung:Novel Mg composite was fabricated to explore the synergetic effect of GNPs and MgOs on the microstructure evaluation, deformation behavior and mechanical properties of Mg–Sr–Ca alloy. The addition of hybrid reinforcement into the Mg–Sr–Ca alloy led to considerable grain refinement (~53%). The GNPs were homogeneously dispersed in the matrix alloy where they were randomly distributed revealing the pulling out and pulling off performance. The MgOs were accumulated on the surface of GNPs as a result of the synergetic effect of 1 + 1
