The high temperature phase stability characteristics of U–
x
Cr (
x
= 0, 1, 2, 3, 4, 5, 7, 9, 15 wt%) alloys have been investigated by dynamic calorimetry under slow heating (1 K min
−1
) in pure flowing Ar-atmosphere. The temperatures of various eutectic, eutectoid solid state phase transformations and that of melting have been measured as a function of Cr-content. These data are used to construct a partial U–Cr phase diagram on U-rich side, which showed good agreement with the recent assessment. The liquidus temperatures for higher Cr-contents, however exhibited a small upward shift as compared to equilibrium phase diagram estimates. The measured transformation enthalpies for the on-heating eutectoid and eutectic transformations exhibited an increase with Cr content of the alloys.
