Abstract:
As a ceramic material, AlN has very good thermophysical and mechanical properties. In addition, AlN is an effective refining agent for Mg alloys because it has a lattice constant similar to that of Mg. Therefore, AlN is an ideal reinforcement for magnesium matrix composites (MMCs), and is attracting increasing attention. This review addresses the development of preparation technologies for AlN-reinforced Mg matrix composites. The mainstream preparation techniques include stir casting, melt infiltration, powder metallurgy, and in-situ methods. In addition, the advantages and disadvantages of these techniques are analyzed in depth, and it is pointed out that the next direction for the preparation of high-performance AlN-reinforced MMCs is less aluminization and multiple technologies integration.
