TLDR
In this paper, the effect of nano-sized Al2O3 particulates as reinforcement and processing type with the micro-structural and tensile properties of magnesium was investigated, and the results showed that the overall combination of tensile property of these materials remained superior when compared to high strength magnesium alloy AZ91 reinforced with much higher weight percentage of SiC Fractography studies revealed that the typical brittle fracture of pure magnesium changed to ductile due to the incorporation of nanoAl2O 3 particulates, while powder metallurgy processed material exhibited superior yield strength and ultimate tensile strengthAbout:

Enhanced properties of Mg-based nano-composites reinforced with Al2O3 nano-particles
TL;DR: In this paper, nano-particles were added to pure Mg and AZ31 magnesium alloy via a stir-casting method, and the results showed that the presence of nanoparticles significantly increased yield stress and tensile strength but decreased the ductility of both pure magnesium and AZ 31.

Prediction models for the yield strength of particle-reinforced unimodal pure magnesium (Mg) metal matrix nanocomposites (MMNCs)
Chang-Soo Kim,Il Sohn,Marjan Nezafati,J. B. Ferguson,Benjamin F. Schultz,Zahra Bajestani-Gohari,Pradeep K. Rohatgi,Kyu Cho +7 more
TL;DR: In this article, the authors examined the yield strength of particle-reinforced MMNCs by considering individual strengthening mechanism candidates and yield strength prediction models and found that the incorporation of the coefficient of thermal expansion mismatch and modulus mismatch will considerably overestimate the experimental yield strength.
