Abstract

See full text

Production methods for Ti—Al alloys may include: adding a flux including calcium oxide containing 35+wt. % calcium fluoride, to a melt starting material of Ti material and Al material and with 50+wt. % Al; introducing the fluxed melt starting material into a water-cooled copper crucible having a tapping port in the bottom, induction melting it inside the water-cooled copper crucible in at least a 1.33 Pa atmosphere; the flux, containing oxygen released from the melt starting material by the induction melting, is separated out by tapping the melt starting material, which was induction melted in the water-cooled copper crucible, downward from the tapping port; and when obtaining the Ti—Al alloy by casting the flux-removed melt starting material, the induction melting output is reduced to no more than 90% of that during melting and tapping is performed from the water-cooled crucible with the output in a reduced state.
