Microstructure, thermal and mechanical response of AZ51/Al2O3 nanocomposite with 2wt.% Ca addition

In the present study, new AZ51/Al2O3–2Ca magnesium nanocomposite was successfully synthesized by simultaneously adding 2 wt.% aluminum, 2 wt.% Ca and 1.5 vol.% nanosized Al2O3 (50 nm) into AZ31 matrix using a disintegrated melt deposition (DMD) technique. AZ51/Al2O3 nanocomposite was developed following the same processing route except adding Ca. Composite samples were then subsequently hot extruded at 400 °C and characterized. Microstructural...
