Abstract

Undercooling and solidification phenomena of Cu and Cu-O and Cu-S alloys were investigated. The "one-way nucleation" of Cu/Cu₂S eutectic was also examined. The undercooling of Cu-O and Cu-S alloys increased with increasing oxygen or sulfur content. This may be caused by oxidation or sulfurizing of effective nucleants in molten copper, or by the surfactant roll of oxygen and sulfur. Regarding the "one-way nucleation", the Cu phase nucleates the Cu₂S phase at small undercooling, but the Cu₂S phase does not nucleate Cu.
