Focusing on the plastic anisotropy between basal and prismatic slip in Mg alloys, I Focusing on the plastic anisotropy between basal and prismatic slip in Mg alloys, I explored the high formability magnesium alloys design. The plastic anisotropy factor was obtained from the first-principles calculations. I fabricated the magnesium alloys and evaluated their formability by Erichsen tests. As a result, the lower plastic anisotropy factor obtained from the first-principles calculations, the higher plastic formability in the magnesium alloys, with an exception. The reason why the plastic anisotropy factor did not correspond to the formability is that the slip system other than the basal and prismatic slip was activated by alloying elements. It is suggested that it is necessary to determine another plastic anisotropy factor including other slip systems for designing high formability magnesium alloys
