Abstract

This paper shows that systematic experimental studies of phase equilibria and thermochemistry in the (Zr, Hf) vs (Nb, Ta) systems, as well as the other systems would be of great value in verifying the predictions of periodic system effects analyses, and refining the Gibbs energy descriptions. In particular, studies of the Pt-W, Ru-V and Os-V systems could provide new insight into the treatment of the non-stable forms of the transition elements. Some of the works point to the possible existence of dynamical instabilities in non-stable phases at 0 K. In principle, it is still possible that some of these unstable modifications become dynamically stable at high temperatures, in the range of CALPHAD type analyses.
