Influence of Mechanical Loading and Temperature on the Magnetic Properties of FeCo-2V Soft Magnetic Alloy
… findings were reinforced by synchrotron XRD and Williamson–Hall results, which confirmed that Lüders band propagation is accompanied by inhomogeneous strain development. Magnetic characterisation further demonstrated that dislocation accumulation increases coercivity and hysteresis losses, …

Molecular Dynamics and X-ray Powder Diffraction Simulations: Investigation of nano-polycrystalline microstructure at the atomic scale coupling local structure configurations and X-ray powder Diffraction techniques
… with the results of traditional LPA (e.g. Williamson-Hall plot and Warren-Averbach method). The D-PDF opens a new chapter in powder diffraction as new insights and a more sound interpretation of the results are made possible with this new approach to diffraction LPA.

Study of microstructure evolution in F/M steel T91 by in-situ synchrotron wide-angle X-rays scattering
… (FWHM), was carefully analyzed using modified Williamson-Hall (W-H) plots to separate strain and crystalline size effects due to their different theta dependence. It was found that dislocation density rho in Fe matrix behaved differently within different tensile regimes: before Ultimate Tensile …

Effects of Laser Shock Peening on Residual Stress, Texture and Deformation Microstructure of Ti-6Al-4V Alloy
… microstructure and texture evolution is still challenging. The present study was undertaken to develop a basic understanding of the effects of LSP on the residual strain/stress distributions, texture evolution and deformation microstructural changes in Ti-6Al-4V alloy. Scanning Electron …

Quantification of fatigue damage in AISI 316L stainless steel using X-Ray powder diffraction (XRD)
… mechanical components with respect to economic challenges. Thus, the comprehension of materials and their behaviour in a typical operating environment is key to enabling and aiding capabilities in component life assessments. Fatigue damage is among the major issues in engineering, because it …

The role of microstructure on the combustion and impact behavior of mechanically activated nickel/aluminum reactive composites
… and strain relaxation on the reaction kinetics. Williamson-Hall analysis suggests that recovery occurs at an annealing temperature of 403<em>K,</em> resulting in lower strains for both Al and Ni. At an annealing temperature of 460 <em>K,</em> both recovery and Al grain growth was observed along …

High Intensity Ultrasound Processing of AlNi (50 wt.% Ni) Particles for Electrocatalytic Water Splitting
… present in the alloy using the Scherrer and Williamson–Hall methods, it was revealed that a temperature gradient that propagates in sonicated metal particles, triggers atomic diffusion and leads to an increase in crystallites’ sizes and reduction of microstrain in the system. The method …
