An improved X-ray diffraction analysis method to characterize dislocation density in lath martensitic structures

An improved X-ray diffraction line profile analysis method is developed to determine dislocation density of lath martensitic steels. This method combines the modified Warren–Averbach (MWA) and the modified Williamson–Hall (MWH) methods. The developed method is robust and leads to unique values for the dislocation density, the effective outer cut-off radius of the dislocations (Re) and the dislocations distribution parameter (M).
