Abstract: 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.

Abstract: An ultrasonic probe and method for noninvasively monitoring materials processing in screw driven extruders. The noninvasive probe includes at least one ultrasonic transducer operable to transmit an ultrasonic signal on a signal path intersecting an inner sidewall of a barrel of the extruder and material between the inner sidewall of the barrel and an outer surface of a screw within the barrel. Information about the state of the material intersected by the ultrasonic signal is ascertainable from an elapsed time between reception of a first reflection of the ultrasonic signal and reception of a second reflection of the ultrasonic signal. The first reflection results when the ultrasonic signal exits the inner sidewall of the barrel and the second reflection results when the ultrasonic signal reaches one of the outer surface of the screw and partially solid material.

Abstract: 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.
