Effects of alloying element on the mechanical behavior of Mg-MMCs: A review

Due to their superior mechanical qualities and high strength-to-weight ratio when compared to unalloyed magnesium, magnesium alloys are widely used in a variety of applications. While maintaining control over the rate of corrosion for materials made of magnesium is crucial in the biological environment. Prior to controlling the degradation rate, Alloying is evaluated as the most essential way to enhance the corrosion and mechanical characteristics of the composites on comparing to the unalloyed material. Therefore, it is a pre-requisite to decide on the suitable alloying element to be added to the metal matrix composite that has a positive influence on the material property. In selecting the alloying elements, biocompatibility, biodegradability, less stress shielding effect, bio-activeness, and non-toxicity are the important parameters for biomedical applications other than mechanical and corrosion properties. The current study evaluated the various alloying elements in the Mg-based materials including Al, Ca, Al, Zn, rare earth (RE), Mn, Bi, Zr, Si, Ag, Zn, Ca, etc in a detailed version.
