SOLUBILITY OF CARBON IN LIQUID AL AND STABILITY OF AL4C3

[摘要] Using thermodynamic models the properties of the Al-C liquid phase have been evaluated from experimental information on the carbon solubility in liquid Al. After slight modification of the description of Al4C3 presented by Gluschko and Gurvitch [1], the solubility has been described very well from 950 to 2500 degrees C with a regular solution model for the liquid phase. Stability of Al4C3 was examined through thermodynamic calculations under various conditions. It has been shown that the description of Al4C3 can account very well for most thermochemical measurements in a wide temperature range.
