Title:
TITANIUM PLATE
Document Type and Number:
WIPO Patent Application WO/2023/084746
Kind Code:
A1
Abstract:
A titanium plate according to one aspect of the present invention has a chemical composition comprising, in % by mass, 0.02% to 0.15% of O, 0.02% to 0.20% of Fe, 0 to 0.08% of N, 0 to 0.100% of C, 0 to 0.013% of H and a remainder comprising Ti and impurities, in which the value of X1+X2-X1&2 is 0.075 or less wherein the crystal orientation of an α-phase is expressed in an Euler angle g = (φ1,Φ,φ2), the area ratio of the α-phase in such a crystal orientation that the absolute value of the misorientation relative to (0°,90°,0°) falls within 30° is defined as X1, the area ratio of the α-phase in such a crystal orientation that the absolute value of the misorientation relative to (0°,90°,30°) falls within 30° is defined as X2, and the area ratio of the α-phase in such a crystal orientation that the absolute value of the misorientation relative to each of (0°,90°,0°) and (0°,90°,30°) falls within 30° is defined as X1&2.
