Abstract

The phase relations for the Co-rich portion of the system U-Co using as-cast samples and heat-treated ones at 700°C/530 h and 1000°C/310 h are studied. The results confirm the Co-rich eutectic point at 13 at.% U, the interval 16.1 to 17.2 at.% U as the solubility range for the U₂Co₁₁ phase, and three magnetic transitions for alloys containing this phase. The importance of the thermomechanical history of the samples for the appearance of the magnetic transitions is indicated
