Magnesium alloys are widely employed throughout various industries due to their lightweight nature and excellent castability. However, they often suffer from limitations regarding mechanical strength. To overcome this, the addition of rare earth (RE) elements has emerged as a promising strategy for enhancing their mechanical properties. RE additions can effectively refine the grain structure, promote precipitation hardening, and form secondary phases, leading to significant improvements in yield strength, tensile strength, and hardness. Furthermore, these elements can also affect the alloy's toughness. The selection of RE content and its combination with other alloying elements is crucial for achieving a desired balance between mechanical properties and other attributes such as corrosion resistance.
