Thermodynamic Calculation Method for Formation of Rare Earth Inclusions in Conductive Copper

摘要

The thermodynamic calculation method for the formation of rare earth inclusions in conductive copper was discussed. After the formation sequence was calculated, the thermodynamic condition for the interchange between RE inclusions was further calculated. As an example, thermodynamic law of the formation for all kinds of cerium inclusions was discussed in conductive copper alloyed by cerium. The theoretical results are shown to be in good agreement with the experimental results.
