摘要：
This paper studied the microstructure and corrosion behavior of Mg-xSc binary alloy (x = 0.1-1.5 wt.%) sheets. Sc has a significant effect of refining grains of Mg. The Mg-Sc binary alloys had a single-phase microstructure for Sc concentrations between 0.1 - 0.3 wt.%, while there were Mg-Sc precipitates for higher Sc concentrations. The Sc additions obviously improved the corrosion resistance of pure Mg due to the refinement of microstructure and the formation of a more protective corrosion products film. The corrosion rate firstly decreased and then increased with increasing Sc concentration. Mg-0.3Sc has the lowest corrosion rate.
