X-Ray Line Profile Analysis of Deformed Austenitic Stainless Steel Plate

Abstract

Although a number of studies have been carried out on the X-ray line profile analysis of metal filings, only few have dealt with bulk metals. The purpose of this paper is to examine whether the Garrod's method, one of the X-ray Fourier analysis methods using a single reflection, is applicable to analyze the X-ray line profile of bulk metals.
The effect of the degree of tensile deformation on the particle-size and the lattice strain of austenitic stainless steel plates was measured by the Garrod's method and by the Integral breadth method.
The Garrod's method gave the results that the particle-size decreased linearly with increasing deformation over the range of deformation from 2 to 20%, while the lattice strain increased linearly up to 8% deformation and then reached a saturation value at 20% deformation. These results were consistent with those obtained by the Integral breadth method, although the former values were smaller than the latter. The similar result had been also recognized in the case of metal filings.
It was, therefore, concluded that the Garrod's method is applicable to the X-ray line profile analysis of the deformed austenitic stainless steel plates and the result obtained by this method is quite reliable.
