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.

摘要： A bond coat (20) of a thermal barrier coating system for components designed for use in a hostile thermal environment, such as turbine, combustor and augmentor components of a gas turbine engine. The composition of the bond coat (20) has graded thermal expansion properties that moderate the transition between a metal substrate (10) and a thermal-insulating ceramic layer (12) of a TBC protecting the substrate (10), while also reducing the service temperature of the bond coat (20) so as to reduce its rate of oxidation. Preferably, the bond coat (20) has multiple layers (20a, 20b, 20c), with the coefficients of thermal conductivity of the individual bond coat layers (20a, 20b, 20c) being very close to that of the substrate (10) in order to promote heat transfer from the outward layer (20c) of the bond coat (20) to the substrate (10). By minimizing the service temperature of the bond coat (20) while grading the thermal expansion properties through the coating system, a more spall-resistant coating system is achieved. The inward layer (20a) of the bond coat (20) preferably contains a metallic constituent, such as an aluminum and/or chromium-containing intermetallic, MCrAl and/or MCrAlY, a middle layer (20b) of the bond coat (20) also contains the metallic constituent in addition to a chromium phase, and an outward layer (20c) of the bond coat (20) contains the chromium phase and at least one platinum-containing phase. The middle and outermost layers (20b, 20c) may also contain chromium carbides such as Cr.sub.3 C.sub.2.
