Abstract Scope |
In recent years, magnesium is expected to be used as a structural material in vehicles. Since limited slip systems in magnesium induces marked yield anisotropy and poor deformability at room temperature, there is a certain demand for developing magnesium alloys having improved plastic anisotropy. In this study, we focused on the Mg-Al system alloy, which is widely used in commerce, and examined a third element that contributes to improve the plastic anisotropy. Generalized stacking fault energy (GSFE), which corresponds to the energy for sliding atomic layer along a slip plane, was calculated in the first-principles calculations to estimate deformability of ternary Mg-Al-X alloys adding the third element, X, to the Mg-Al binary alloy. As a result, it was suggested that the addition of zirconium contributes most to the reduction of plastic anisotropy. Mechanical characterization revealed the effect of the third element on the deformability at room temperature. |
