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 into the titanium article.

摘要： A process for positioning at least one defect in a billet being forged into an article is described. The size and location of the billet is first determined, using a non-destructive test such as ultrasonic inspection. The movement of the defect under selected forging conditions is then predicted, using a finite element analysis model. The billet can then be positioned and forged under conditions which cause the defect to move to a non-critical area of the article. In this manner, a billet which might otherwise be discarded or set aside can often be retained for a useful purpose. Related articles are also described.

摘要： A method is set forth for processing titanium and titanium alloys into titanium articles, in which the titanium exhibits enhanced ultrasonic inspection results for determining its acceptability in microstructurally sensitive titanium applications. The method for processing titanium comprises providing titanium at a temperature above its &bgr;-transus temperature; quenching the titanium from a temperature above the &bgr;-transus temperature, the step of quenching titanium forming an &agr;-plate microstructure in the titanium; and deforming the quenched titanium into a titanium article, the step of deforming the quenched titanium transforming the &agr;-plate microstructure into discontinuous &agr; particles without crystallization textures. The discontinuous-randomly textured &agr; particles lead to a reduction in ultrasonic noise during ultrasonic inspection.

摘要： An ultrasonic inspection method for inspecting titanium material is provided. The ultrasonic inspection method is capable of detecting critical flaws in the titanium material that may limit titanium material applications. The ultrasonic inspection method comprises fixing at least one of frequency or acoustic entity size of the titanium material as a constant for the ultrasonic inspecting; wherein the frequency that is fixed is selected based on the size of the flaws deemed critical for mechanical performance—including fatigue performance—in the titanium material, and the grain size that is fixed selected based on the size of the flaws deemed critical for mechanical performance—including fatigue performance—in the titanium material; ultrasonic inspecting the titanium material in which the step of ultrasonic inspecting the titanium material generates scattering from microstructural characteristics and features of the titanium material; detecting generated scattering; characterizing the type of detected scattering; and determining if the titanium material comprises critical flaws based on the type of scattering. If the scattering comprises predominantly Rayleigh scattering, the step of determining determines that the titanium material comprises uniform-fine grain titanium, however, if the scattering comprises Rayleigh scattering and other types of scattering, the step of determining determines that the titanium material may comprise critical flaws that may limit applications of the titanium material. The invention also provides a system for implementing the method, as embodied by the invention.
