Temperature-Dependent Generalized Planar Fault Energy and Twinnability of Mg Microalloyed with Er, Ho, Dy, Tb, and Gd: First-Principles Study

<div>(a) The values of Helmholtz free energy as a function of unit cell volume of pure Mg between 0 and 600 K at every 100 K. The minimum value depicted by red circle of every fitted curve is the equilibrium volume at corresponding temperature. (b) The equilibrium volume of pure Mg as a function of temperature.</div>
