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.
