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： Ultrasonic inspection system, method, and apparatus for subsurface ultrasonic inspection of curved objects. The inspection system includes an apparatus having a support structure for supporting a selected transducer and a selected acoustic mirror adapted for immersion in a coupling fluid. The total inspection path distance for the ultrasonic radiation includes a first portion defined by the transducer-to-mirror distance, and a second portion including the mirror-to-object distance. The first and second portions may be relatively adjusted within a constant total inspection path distance to focus the ultrasonic radiation at a desired subsurface depth. Selection of the transducer is at least partly dependent on subsurface depth of the desired inspection zone. Selection of the acoustic mirror is at least partly dependent on the selected transducer, the total inspection path distance, and curvature of the inspection object.
