摘要

The enthalpies of mixing of binary liquid alloys of Co-Ce and Co-Sm (in the Sm-rich composition region) were measured by isoperibolic calorimetry. The experimental data show exothermic effects of alloy formation, in agreement with previously measured enthalpies of mixing of cobalt with the lanthanides. The values of the limiting partial enthalpies of mixing in the Co-Ce system are DELTA H_(Co)~0=-34.0+-2.9 kJ mol~(-1) and DELTA H_(Ce)~0=-87.6+-5.8 kJ mol~(-1), and DELTA H_(Co)~0=-50.5+-3.9 kJ mol~(-1) in the Co-Sm system.
