| description | There have been remarkable improvements in the research field of magnesium over the last few decades, especially in the magnesium metal matrix composite in which micro and nanoparticles are used as reinforcement. The dispersion phase of nanoparticles shows a better microstructural morphology than pure magnesium. The magnesium metal matrix nanocomposite shows improved strength with a balance of plasticity as compared to the traditional magnesium metal matrix composite. In this research, Nb<sub>2</sub>O<sub>5</sub> (0 wt.%, 3 wt.%, and 6 wt.%) nanoparticles were used to reinforce AZ31 with the stir casting method, followed by heat treatment, and finally, an investigation was conducted using microstructural analysis. Factors such as the degree of crystallinity, crystallite size, and dislocation density are affected by the concentration of Nb<sub>2</sub>O<sub>5</sub> and heat treatment. With the compositional increase in Nb<sub>2</sub>O<sub>5</sub> weight percentage, the grain size decreases up to 3% Nb<sub>2</sub>O<sub>5</sub> and then increases gradually. The SEM image analysis showed a grain size reduction of up to 3% Nb<sub>2</sub>O<sub>5</sub> and fracture morphology changed from basal slip to a mixture of basal slip and adiabatic shear band. |
