摘要： A method and system for microstructural evaluation and degradation evaluation of an object are provided. The method comprises insonifying at least one subvolume of the object with ultrasonic energy at a fundamental frequency and acquiring receive energy from the object at the fundamental frequency and at least one harmonic frequency thereof. A nonlinearity parameter is determined using the receive energy. The nonlinearity parameter is then used to determine a grain size for the subvolume of the object and a variation of the grain size within the object. The nonlinearity parameter is also used to determine fatigue damage or a residual stress.

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 ultrasound inspection system is provided. The ultrasound inspection system includes a pulse echo transducer and a processor that is operationally coupled to the transducer. The system facilitates reducing noise in an echo received from a near surface inspection area of a component. To facilitate reducing noise the processor is programmed to extract an A-scan data set from a B-scan image of the component. The processor is also programmed to locate a half-max point of a front surface echo in the A-scan data set. The processor is also programmed to locate the front surface of the component using a first zero crossing in a derivative of the A-scan data set.

摘要： A method of inspecting a component includes immersing the component in a coupling medium with material velocity cw and immersing an ultrasonic (UT) probe having at least one transducer in the coupling medium. The UT probe has a convex lens with acoustic velocity cL and an acoustic impedance less than about 2.5×106 Rayls. The method further includes exciting the transducer to produce an UT pulse directed into the component and generating echo signals using the transducer as a receive element. An US inspection system includes UT probe, a pulser/receiver configured to supply signal excitation pulses to the transducer element at a pulse repetition frequency (prf) of at least about 1000 Hz and a scanner configured to scan the component with the UT probe at a scanning rate equal to the prf times a scanning increment.
