Deconvolution-based peak profile analysis methods for characterization of CoCrFeMnNi high-entropy alloy.

In this study, we compare several peak profile analysis methods for the investigation of the CoCrFeMnNi high-entropy alloy (HEA) after the plastic deformation. We show that Williamson - Hall (WH) approach poorly correlates with measured peak broadening and some corrections must be introduced to improve the analysis. The correction for elastic modulus for different crystallographic directions or application of Williamson Hall (WH) and Warren - Averbach (WA) methods significantly improve the correlation between the model and experimental data.
