Abstract
A high-strength α+β type hot-rolled titanium alloy sheet containing 0.8 to 1.5 mass % Fe, 4.8 to 5.5 mass % Al, 0.030 mass % N, O and N, wherein cracks are prevented from spreading, wherein: (a) ND represents normal direction of a hot-rolled sheet; RD represents hot rolling direction; TD represents hot rolling width direction; θ represents the angle formed between c axis and ND; φ represents angle formed between plane including c axis and ND, and a plane including ND and TD; (b1) XND represents highest (0002) relative intensity of X-ray reflection by grains when θ is from 0° to 30° ; (b2) XTD represents the highest (0002) relative intensity of the X-ray reflection caused by grains when θ is from 80° to 100° and φ is ±10° . (c) The high-strength α+β type hot-rolled titanium alloy sheet has a value for XTD/XND of at least 4.0. Q(%)=[O]+2.77·[N].
