The effect of cooling rate and composition on the transformation of the gamma-phase in uranium ruthenium alloys (with an appendix on ruthenium as a grain-refining element)

Calphad thermodynamic description of some binary systems involving U

“…From their figure it seems that they consider their results as the highest homogeneity limit for the a-U and b-U phases (a-U a-U + b-U and b-U b-U + c-U ) or the invariant eutectoid. The accuracy of these results is not better than the older ones in this area [49,50,47].…”

Characterization of cubic γ-phase uranium molybdenum alloys synthesized by ultrafast cooling

“…The data may consequently indicate the presence of c-U in small quantities (<5%). We notice here that the existence of the so-called double (a + c) phase was already found in U-1.5 w.% Mo ($3.5 at.% Mo) [6]) or in U-2.5 at.% Mo [11].…”
