摘要： 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.

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 silicide-based composite toughened with a niobium-based metallic phase, and further containing a phase that significantly improves the oxidation resistance of the composite. The oxidation-resistant phase is a chromium-based Laves-type phase modified with silicon, which has been shown to greatly increase the oxidation resistance of silicide-based composites at temperatures of up to 1200 C. The oxidation-resistant silicide-based composite generally contains one or more silicide intermetallic phases, each of which is an M.sub.5 Si.sub.3 -type phase where M is Nb+Ti+Hf. The niobium-based metallic phase contains niobium, titanium, hafnium, chromium, aluminum and silicon. The silicon-modified Laves-type phase is of the Cr.sub.2 M type where M is Nb+Ti+Hf. A silicide-based composite contains, in atomic percent, about 12-25% titanium, about 6-12% hafnium, about 15-25% chromium, about 1-8% aluminum and about 12-20% silicon, with the balance essentially niobium.
