Fatigue Damage Assessment by X-Ray Diffraction and Nondestructive Life Assessment Methodology
X-Ray diffraction (XRD) has been employed to evaluate cumulative damage incurred under both high cycle fatigue (HCF) and low cycle fatigue (LCF) conditions. Additional objectives of the study were to correlate the x-ray diffraction data to the microstructural characteristics and deformation mechanisms activated by various fatigue regimes and to develop a methodology for nondestructive assessment of remaining life.
