Significance of reinforcement in Mg-based MMCs for various applications: A review

With the ability to replace conventional alloys in mass-saving applications while still providing greater stiffness and strength, magnesium is one of the lightest structural metals currently on the market. When compared to normal engineering materials, the incorporation of reinforcing elements into the metallic matrix significantly affects stiffness, specific strength, wear, and damping behavior, and creep characteristics. Magnesium metal matrix composites are suitable materials for a variety of applications due to their excellent physical and mechanical qualities and low density. This paper provides a summary of the effects of different reinforcements in magnesium and its alloys, highlighting both their advantages and disadvantages. It is carefully explored how reinforcing affects both the mechanical properties and the microstructure.
