Title:
TITANIUM ALLOY PLATE, TITANIUM ALLOY COIL, METHOD FOR PRODUCING TITANIUM ALLOY PLATE AND METHOD FOR PRODUCING TITANIUM ALLOY COIL
Document Type and Number:
WIPO Patent Application WO/2022/162816
Kind Code:
A1
Abstract:
This titanium alloy plate contains a specific chemical component, while having an area ratio of the α phase of 80% or more and an area ratio of the α phase having a circle equivalent diameter of not less than 1 μm of more than 53%. In a (0001) pole figure from the plate thickness direction, the angle between the plate thickness direction and a direction showing the peak of integration degree calculated by the texture analysis of an inverse pole diagram using a spherical harmonics method of an electron backscattered diffraction method, with the expansion index being 16 and the Gauss half width value being 5°, is 65° or less; and the average plate thickness is 2.5 mm or less.
