Abstract

A titanium material production method for producing homogeneous fine grain titanium material in which the titanium material has a grain size in a range from about 5 μm to about 20 μm. The method comprises providing a titanium material blank; conducting a first heat treatment on the titanium material blank to heat the titanium material blank to a β-range; quenching the titanium material blank from the β-region to the α+β-region; forging the titanium material blank; and conducting a second heat treatment on the titanium material blank. The titanium material production method subjects the titanium material blank to superplasticity conditions during part of the titanium material production method.

Description

BACKGROUND OF THE INVENTION

[0001] The invention relates to titanium material production methods. In particular, the invention relates to titanium material production methods that can produce titanium materials suitable for inspection using ultrasonic energy inspection methods and systems.

[0002] The production of titanium material with titanium material grain sizes and nature of αTi particle colony structures may be important variables that influence titanium material applications. Further, size of titanium grains and a nature of αTi particle colony structures may influence the ultrasonic noise and ultrasonic inspection in single phase and two-phase titanium alloys and materials, in which the ultrasonic inspection can be used to determine suitability of the titanium material for various applications. The size of titanium grains and the nature of αTi particle colony structures may influence ultrasonic inspection techniques, methods, and results by creating undesirable noise during u...
