The effect of pre-processing and grain structure on the bio-corrosion and fatigue resistance of magnesium alloy AZ31

Magnesium alloys are considered as candidate materials for temporary implants. Fatigue resistance and controllable rate of corrosion in bodily fluids are essential for such applications. The effect of the grain structure produced by hot rolling and equal channel angular pressing on the fatigue behaviour and the bio-corrosion rate were studied for alloy AZ31. The results suggest that mechanical processing can be used to control both properties.
