摘要： Methods and systems (10) based on guided wave thermography for non-destructively inspecting structural flaws that may be present in a structure (15). For example, such systems and methods may provide the ability to selectively deliver sonic or ultrasonic energy to provide focusing and/or beam steering throughout the structure from a fixed transducer location (12, 14, 16). Moreover, such systems and methods may provide the ability to selectively apply sonic or ultrasonic energy having excitation characteristics (FIGS. 11 and 12) which may be uniquely tailored to enhance the thermal response (FIGS. 5 and 7) of a particular flaw geometry and/or flaw location.

摘要： An inspection method includes driving a plurality of spaced apart transmitting transducer elements with a respective time delay and a respective frequency such that each of the transmitting transducer elements transmits an ultrasonic guided wave through a transmission medium defined by a material having at least one unknown physical property. The ultrasonic guided waves are received at a receiving transducer element disposed at a distance from the transmitting transducer elements. A respective time delay and a respective frequency for each of the transmitting transducer elements is determined that provides a maximum amplitude in a signal received at the receiving transducer element. The plurality of transmitting transducer elements are activated in accordance with the determined time delays and frequencies to transmit inspection signals through the transmission medium. A location of a defect in the material is determined based on velocities of the inspection signals received at the receiving transducer element.

摘要： Systems and methods that use a single-crystal boule SiC sharpened into a cutting tool for ultra-precision machining of ferrous alloys are disclosed. Conventional ultra-precision machining uses single-crystal natural diamond. Despite the exceptional mechanical properties of diamond, its chemical properties have inhibited the extension of ultra-precision machining to iron-containing (ferrous) alloys. A single-crystal SiC cutting tool can be used to cut many materials for which diamond cutting tools are conventionally used. Additionally, a single-crystal SiC cutting tool can be used to cut materials for which diamond cutting tools are inappropriate, such as ferrous metals or nickel.
