Exploratory Nondestructive Evaluation (NDE) Research for Advanced Materials andProcesses and Aging Systems

摘要

A sensor has been developed and tested that is capable of emitting and receivingultrasonic energy at temperatures exceeding 900 C (1652 F) and pressures above 150 MPa (22,500 psi). The sensor works with standard ultrasonic pulser-receivers and has demonstrated the capability of measuring workpiece deformation during hot isostatic pressing (HIP). Details of the sensor design, performance, and coupling of the ultrasound to the workpiece are described. Ultrasonic data acquired by the sensor, in situ, during HIP runs are presented.
