英文摘要
The fine-grain processing of magnesium alloys was investigated for attaining low-temperature superplasticity at high strain rates. The alloys were produced by friction stir processing. Some alloying elements were suggested to be detrimental for grain boundary sliding to occur. In addition, we revealed the high temperature deformation behavior at high strain rates, which corresponds to the strain rates for friction stir processing. Based on these results, we proposed some techniques for friction stir processing, which will enable to increase the area with fine grains.
