WebDislocation densities were extracted from the line profiles using the Convolutional Multiple Whole Profile (cmwp) software (Ribárik et al., 2024).The cmwp software models the line profile intensity I (q), where q is the wavevector magnitude, as a convolution of intensities arising from instrumental effects, size broadening, and, in particular, strain broadening … WebMore recently, the convolutional multiple whole profile (CMWP) X-ray diffraction Line Profile Analysis (XLPA) method [67,68] has been developed to characterize dislocation loops in irradiated ...

Dislocation Density of Electron Beam Powder Bed Fusion …

WebIn the present study, a coarse-grained Cu–0.5 wt% Zr alloy was repeatedly processed by a novel technique of rotational constrained bending (RCB). In this technique, the workpiece was deformed by bending in a channel with an angle of 90°, using a WebThe tensile specimens of 780MPa grade bainitic steel were uniaxially stretched until the plastic strain reached a value of 0.05. We performed CMWP analyses on the obtained diffraction patterns during tensile test with various initial parameters of dislocation density and crystallite size. chip phillips photography

Systematic analysis of the effect of value of R c in the CMWP ...

WebXRD profiles were evaluated using the CMWP software. The results are shown in Fig. 3 which displays the variations of the average crystallite size and the dislocation density in the Ale3Mg alloy ... WebThe present TOF-ND/CMWP approach successfully determined the bulk-averaged dislocation density (6.8 × 10 13 m −2) in the as-built state for the α-matrix, suggesting a non-negligible contribution of dislocation hardening. The obtained dislocation density values were comparable to those obtained by conventional and synchrotron X-ray ... WebThe cmwp software evaluates parameters describing effects of both the specimen size and dislocation broadening of diffraction intensity peaks by first employing a statistical Monte Carlo optimisation followed by the Marquardt–Levenberg non-linear least squares algorithm, see Ribárik et al.
