First-principles studies of structural stabilities and enthalpies of formation of refractory intermetallics: TM and TM3 (TÂ =Â Ti, Zr, Hf; MÂ =Â Ru, Rh, Pd, Os, Ir, Pt)

► Structural phase stabilities of thirty-six refractory compounds have been reported. ► Enthalpies of formation of thirty-six refractory compounds have been derived. ► A relationship between cohesive energies and melting temperatures was derived.
