Abstract

The effect of instrumental correction on X-ray line profile analysis was discussed in cold rolled low carbon ferritic steel. It was confirmed that the effect of instrumental broadening is underestimated by utilizing Gaussian correction in comparison with Voigt correction. The values of micro-strain, which were evaluated by the recently developed direct fitting method, were overestimated slightly in Gaussian correction. As a result, the following equations were established in the relation between micro-strain () and dislocation density () for each case: [m− 2] ≒ 1.5 × 1020 2 (Gaussian correction) [m− 2] ≒ 1.9 × 1020 2 (Voigt correction).
