Abstract
A titanium article for an ultrasonic inspection is provided in which the titanium article can be ultrasonic inspected for determining its acceptability in for microstructurally sensitive applications. The ultrasonic inspection method comprises providing a titanium article, directing ultrasonic energy of ultrasonic inspection to the titanium article; scattering reflected energy in the titanium article; determining an amount of noise generated by the ultrasonic inspection of the titanium article; and characterizing the titanium article as acceptable if the amount of noise as a function of ultrasonic frequency or wavelength is characteristic of predominantly Rayleigh scattering and the magnitude of the noise is less than a pre-determined noise level. The titanium article comprises an uniform-fine grain microstructure. The uniform-fine grain microstructure generates predominantly Rayleigh scattering when undergoing ultrasonic inspection. The invention also sets forth a method of forming a titanium article. The method of forming comprises providing a uniform fine grain titanium material by a processes selected from forging and heat treating a billet of conventional titanium material int…
