Аннотация

The role of MgAl2O4 particles in Al matrix composites has been very crucial. They have evolved from acting as a product at the matrix-reinforcement interface of some ex-situ aluminium matrix composites (AMCs) to a separate reinforcement in the in-situ AMCs. In recent times, they have also been used as a nucleating agent in the form of Al-MgAl2O4 master alloy to propagate the grain refinement process in commercial Al alloys for microstructural changes. In this context, this work reviews the recent developments of MgAl2O4 formation in Al-Mg-Al2O3 and Al-Mg-SiC composites. It summarizes the influence of MgAl2O4 on surface morphology and mechanical characteristics during their formation at the matrix-reinforcement interface. Furthermore, a thorough study on the impact of MgAl2O4 as a reinforcement formed via the in-situ reactive synthesis in AMCs using Al-Mg matrix and different oxide sources namely SiO2, TiO2, and H3BO3 has been carried out. Various results on the grain refinement process obtained using MgAl2O4 as a heterogeneous nucleating agent in Al alloys have been also deliberated in this review.
