Mg alloys are attractive structural materials for light-weight vehicles and electronic devices due to their high strength-to-weight ratio. Fuel efficiency can be improved by the application of Mg alloys to automobiles through weight reduction. Mg alloys are also promising materials for biodegradable implants in the human body. However, the poor corrosion resistance of existing Mg alloys limits their applications. Severe plastic deformation (SPD) is one of the techniques to refine the microstructure of Mg alloys through ultra-fine grains by applying force in different directions. In this work, multi-directional forging and screw rolling at different temperatures have been utilized to manufacture alloys with enhanced mechanical properties and improved corrosion resistance. It was found that SPD can not only increase the mechanical properties but also significantly improve corrosion resistance.
