Abstract
Official abstract text for this publication.
To provide an α-β titanium alloy that has high strength and excellent hot workability of the level of the α-β titanium alloy, typified by the Ti-6Al-4V, while exhibiting more excellent machinability than the Ti-6Al-4V. The α-β titanium alloy includes, in percent by mass: at least one element of 0.1 to 2.0% of Cu and 0.1 to 2.0% of Ni; 2.0 to 8.5% of Al; 0.08 to 0.25% of C; and 1.0 to 7.0% in total of at least one element of 0 to 4.5% of Cr and 0 to 2.5% of Fe, with the balance being Ti and inevitable impurities.
First claim

1 . An α-β titanium alloy comprising, in percent by mass: Ti; at least one element of 0.1 to 2.0% of Cu and 0.1 to 2.0% of Ni; 2.0 to 8.5% of Al; 0.08 to 0.25% of C; and 1.0 to 7.0% in total of at least one element of 0 to 4.5% of Cr and 0 to 2.5% of Fe. 2 . The α-β titanium alloy according to claim 1 , further comprising, in percent by mass: more than 0% and 10% or less in total of one or more elements selected from the group consisting of more than 0% and 5.0% or less of V; more than 0% and 5.0% or less of Mo; more than 0% and 5.0% or less of Nb; and more than 0% and 5.0% or less of Ta. 3 . The α-β titanium alloy according to claim 1 , further comprising, in percent by mass, more than 0% and 0.8% or less of Si. 4 . The α-β titanium alloy according to claim 2 , further comprising, in percent by mass, more than 0% and 0.8% or less of Si.
