Abstract
It is well known that the fatigue cycling of crystalline materials can lead to detectable changes in the. x-ray diffraction-line profiles. As the full width at half maximum (FWHM) can be more easily derived from the line13; profile than other parameters such as variance or the Fourier co-efficients.many investigators(1-10) have studied the effect of fatigue cycling on the FWHM of the diffraction line. The studies pertaining to the effect of fatigue cycling on Fourier coeffients are limited(8,11,12). The results on steel(1-8),iron(3), aluminium(9,10), and silicon, gold and aluminium alloy(9) indicate13; that the ( b/b ) versus N curve (where N is number of fatigue cycles, and bo and b are the FWHMs,respectively, for the specimen before and after N cycles)in general shows three distinct stages. Fig.1 shows this curve for annealed specimen of aluminium when the measurements are made using CuK, radiation, so that diffraction occurs, from the near-surface reqion.6.Ohuchi
