Rh-Zr (Rhodium-Zirconium) D. Arias and J.P. Abriata The assessed Rh-Zr phase diagram is primarily based on the work of [64Ram, 65Zeg, 78Ere, 80Ere, and 88Jor]. It differs from those given in previous evaluations. Good agreement exists between the results of [80Ere, 88Jor], and most of the temperature and composition values are averages calculated from the corresponding values given by these authors. Nevertheless, it is clear that more experimental work is needed to further clarify the phase diagram of the Zr-Rh system mainly in connection with the stability ranges of the intermediate phases. The maximum solubility of Zr in (Rh) is ~11 at.% at 1730 C. The superconducting properties of stable and metastable Zr-Rh alloys in the composition range 0 to 50 at.% Rh were studied by [65Zeg] and [88Jor], among others. 64Ram: A. Raman and K. Schubert, Z.
