PROBLEM TO BE SOLVED: To provide an α+&bgr; type titanium alloy plate which has high strength and is excellent in bendability, and a method of manufacturing it.SOLUTION: An α+&bgr; type titanium alloy plate includes 2.0-4.5 mass%, by Mo equivalent, of at least one of all solid solution type &bgr; stabilizing elements, 0.3-2.0 mass%, by Fe equivalent, of at least one of eutectoid type &bgr; stabilizing elements, and over 3.0 mass% and not more than 5.5 mass%, by Al equivalent, of at least one of α stabilizing elements, with the balance being Ti and inevitable impurities. The average particle size of an α phase is 5.0 μm or smaller, the maximum particle size of the α phase is 10.0 μm or smaller, the average aspect ratio of the α phase is 2.0 or lower, and the maximum aspect ratio of the α phase is 5.0 or lower. |
