Document Type and Number:
WIPO Patent Application WO/2019/155553
Kind Code:
A1
Abstract:
A titanium alloy material which contains, in mass%, from 0.7% to 1.4% of Cu, from 0.5% to 1.5% of Sn, from 0.10% to 0.45% of Si, from 0.05% to 0.50% of Nb, from 0.00% to 0.08% of Fe and from 0.00% to 0.08% of O, with the balance being made up of Ti and impurities. This titanium alloy material is configured such that: the area fraction of α phases in the structure is 96.0% or more; the area fraction of intermetallic compounds is 1.0% or more; the average crystal grain size of the α phases is from 10 μm to 100 μm (inclusive); and the average particle size of the intermetallic compounds is from 0.1 μm to 3.0 μm.
