摘要: Abstract In this paper, research and developmental efforts that demonstrate high sensitivity detection characterization of defects assessment microstructural degradation, residual stresses fatigue damage in materials using different non-destructive evaluation (NDE) techniques, have been discussed. Applications eddy current techniques for quantitative defect generalized applications, remote field technique inspection steam generator heat exchanger tubes Advanced ultrasonic methods such as time flight diffraction, synthetic aperture focusing technique, phased array signal processing detection, imaging ultrasonics magnetic Barkhausen emission microstructures acoustic infrared thermography weld quality critical nuclear components part intelligent (IPM) work Application integrity pressurized has Development a software called assets infrastructure management system (AIMS), storing retrieving information various materials, systems, also highlighted. The applications discussed are result systematic innovative R&D the multidisciplinary areas physics, instrumentation, sensors softwares providing solutions to challenging problems.
