Calculated formation Eform and energies Ecoh of X = V, Cr, and Mn sitting at Al and Ti sites in γ (a) and β0 (b) phases as a function of composition. The relative energy ΔE denotes the energy difference between Al-site and Ti-site, and positive (negative) value means that Ti (Al) site is energetically favored. To simulate the low level doping 3 × 3 × 3 (1.825 at.%) and 2 × 2 × 2 (6.25 at.%) supercells are constructed with the central atom replaced by X.
