CONTINUOUS CASTING METHOD OF Cu-Ga ALLOY

摘要

PROBLEM TO BE SOLVED: To provide a continuous casting method of a Cu-Ga alloy capable of producing a high quality Cu-Ga alloy ingot where an oscillation mark depth is shallow and the concentration segregation of Ga is suppressed.SOLUTION: In a continuous casting method of a Cu-Ga alloy containing Ga in a range of 15 atom% or more and 35 atom% or less and the balance Cu with inevitable impurities, an ingot is drawn out from a mold while performing mold oscillation or the intermittent drawing out of the ingot. In the mold oscillation or the intermittent drawing out of the ingot, 0.1
