Figure 2
(Left) The derived enthalpies of formation predicted by variable-composition evolutionary computations for the W–B system. Each square represents an individual structure and the most stable ground-state phases (solid circles) are connected to form a convex hull. (Right) In order to clarify the convex hull, the formation enthalpy is plotted as a function of composition for selected structures of the USPEX-predicted tungsten borides, including all the lowest-enthalpy ground-state phases on the convex hull.
