(a) The map of total energy (units of mRy) for the hcp phase of TiZrHf as a function of the Wigner-Seitz radius w and the hexagonal axial ratio c/a. The energies are plotted relative to the energy minimum. (b) The optimized c/a ratio for the hcp phase of TiZrHfTax as a function of composition. (c) The equilibrium w for the bcc, fcc and hcp phases of TiZrHfTax as a function of composition.
