Structure and Low-Temperature Properties of U-15 at.% T Alloys (T = Mo, Nb, Pt, Ru, Ti)

Abstrakt

We show that the high-temperature cubic gamma-U phase can be retained to room temperature by means of ultrafast-cooling technique (with a cooling rate in the range of 10(6) K/s) combined with alloying with selected 4d and 5d elements in the IV-VIII group of the periodic table Hofman et al. (Proceedings of the International meeting on Reduced Enrichment for Research and Test Reactors (RERTR), Sao Paulo, Brazil, pp. 18-23 1998 [1]). Most of U-15 at.% T alloys (atomic percentage, T = Mo, Nb, Pt, Ru, and Ti) revealed the single cubic phase (or dominant cubic phase).

All our investigated samples become superconducting below 2.11 K.
