In this article, application of various non-destructive evaluation (NDE) techniques for assessment of creep and fatigue damage in materials and components has been discussed. X-ray diffraction technique has been used for finding fabrication-induced residual stresses in components. Ultrasonic and magnetic techniques have been applied for characterizing changes in microstructures due to creep and fatigue. Crack closure phenomenon and fatigue crack growth have been studied in austenitic stainless steels using acoustic emission technique. Dual-frequency eddy current technique has been used for high sensitive detection of fatigue cracks in compressor discs of aeroengines.
