摘要
First-principles electronic structure calculations and the cluster variation method (CVM) are used to study phase stability for the three binary systems of the ternary Ru-Zr-Nb system. The results are used to assess conflicting experimental data on the stability of the Ru3Nb compound. The possibility of stabilizing the high-pressure phase (L1(2) structure) of Ru3Nb by substitution of Zr for Nb and, further, the tetragonal distortion reported in Nb-rich alloys is evaluated in light of the electronic structure calculations.
