TL;DR: In this paper, an attempt has been made to fit the X-ray intensity profiles by Fourier series and transforms, and the result is discussed, where the similarity in structure of the negative wedge built-up-edge and the secondary shear zone is also analyzed.
Abstract: The study of recrystallisation in metal cutting is of significant importance since it influences tool wear and surface finish. The formation of recrystallised crystallites in the secondary shear zone (flow layer) when machining mild steel with HSS tools and the determination of size of such crystallites by X-ray diffraction techniques were reported by the author in earlier papers. In this paper an attempt has been made to fit the X-ray intensity profiles by Fourier series and transforms. Computer programmes have been developed for solving Fourier series and the result is discussed. The similarity in structure of the negative wedge built-up-edge, and the secondary shear zone is also analysed. The changes in X-ray diffraction patterns give a vivid picture of metallurgical changes in the flow layer. Fourier analysis lends sophistication to the analytical approach to the X-ray diffraction technique.
