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 method for inspecting a component includes exciting a number of transducers forming an array to produce an ultrasonic transmission beam (beam) focused into the component. The array and the component are separated by a standoff. A number of echo signals are generated using the transducers, and the echo signals are processed in a number of channels. The processing includes both dynamical focus and providing a dynamic aperture on receive, both of which compensate for refraction of the beam at the component/standoff interface. A single-turn inspection method includes: (a) positioning the array facing the component, (b) exciting the transducers, (c) generating a number of echo signals, (d) changing the relative angular orientation of the array and the component around an axis and repeating steps (b) and (c), and (e) processing the echo signals to form at least one processed echo signal.

摘要： An exemplary apparatus for determining the thicknesses of individual layers in a multilayer article comprises an ultrasonic transducer coupled to the multilayer article with a buffer rod of similar acoustic properties, a pulser-receiver-amplifier which generates ultrasonic waves to produce discernible, time resolved pulse echoes, a digitizing oscilloscope which may be used to view the received pulse echoes, and a computer for controlling data acquisition and analysis. The computer is programmed to execute the exemplary method, which comprises the steps of selecting a center frequency of a transducer such that respective pulse echoes produced at the interfaces between layers of the multilayer article each have a common distinguishing feature with a signal to noise ratio greater than or equal to a predetermined value, and the pulse echoes are resolved in time; determining a transit time correction factor for the layer of the multilayer article based on an actual transit time measured with the transducer adjacent to the layer and an apparent transit time measured with the transducer not adjacent to the layer; propagating a pulse through the multilayer article to produce pulse echoes at the interfaces between the layers of the multilayer article; determining a measured transit time of the pulse through the layer based on the pulse echoes at the interfaces of the layer; and calculating a thickness of the layer based on the measured transit time and the transit time correction factor.
