摘要：

The solubility of cobalt in α thorium is described by the equation cs(at.% Co) = 10970 exp(-13844/T). The heat of solution is -115.2 kJ mol- Co and the terminal solubility at the eutectic temperature 1100 °C is 0.46 at.% Co. A newly identified metastable phase with a plate morphology is present in thorium-rich alloys on quenching from the high (αTh) region. Upon aging for different times at 500 °C and above, this phase transforms to rod-like particles of Th7Co3. © 1990.
