Cmwp dislocation
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 WebCMWP has been systematically run on the two diffraction patterns by starting with initial dislocation density values, ρ initial in the range of 1-300 [10 14 m-2] for the Nb and in the range of 1-1000 [10 14 m-2] for the HEA patterns, respectively. Four optimization algorithms have been tested.

The evolution of dislocation density (ρ) during the cold swaging evaluated by the CMWP method is shown in Fig. 3 (a).In the CoCrFeMnNi sample, the dislocation density remarkably increased …
WebThe Convolutional-Multiple-Whole-Profile (CMWP) procedure is based on physical profile functions for dislocations, domain size, stacking faults and twin boundaries. Order dependence, strain anisotropy, hkl dependent broadening of planar defects and peak shape are used to separate the effect of different lattice defect types. 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.
