Summary: This study investigated the microstructures, mechanical properties, and strain hardening properties of 1 vol% and 2 vol% (Al3Zr/Al2O3 + ZrB2) nanoparticles reinforced 6016Al matrix composites, which were synthesized through in-situ chemical reaction and solidified under squeezing pressure. It was found that Fe-B-rich and AlB2 phase particles were also formed in addition to the reinforcement particles. The matrix of the 1 vol%-6016Al composite exhibited fine Mg2Si precipitates under high squeezing pressure, while the matrix of the 2 vol%-6016Al composite did not show such precipitates. The squeezed 1 vol%-6016Al composite also had a greater reduction in grain size compared to the squeezed 2 vol%-6016Al composite. The squeezed 6016Al matrix composites exhibited high strength, high ductility, and lower strain hardening effect in the aged state, which was different from monolithic 6016Al alloys.

Summary: Magnesium matrix composites (MMCs) have shown promising mechanical properties at both room and elevated temperatures. The commonly used ceramic particle reinforcements often improve the yield and ultimate stresses but sacrifice ductility. Titanium (Ti) has been introduced as an alternative reinforcement due to its high melting point, high Young's modulus, high plasticity, low mutual solubility with Mg matrix, and similar thermal expansion coefficient. However, challenges remain in achieving Ti's homogeneity, high recovery rate, and optimizing the interfacial bonding strength between Mg and Ti in MMCs. This review focuses on the microstructural characteristics, mechanical properties, and fabrication techniques of Ti-reinforced MMCs, comparing and discussing the influencing factors that govern the strengthening mechanisms.
