Raw image of the thickness of twins under quasi-static and dynamic deformation

Growth characteristics of deformation twins are investigated in a CrMnFeCoNi alloy. The twin thickness of CrMnFeCoNi deformed under different strain rates was examined using multiple high-resolution TEM (HR-TEM) micrographs. The results show the effects of grain size and strain rate on twin thickness, which should be considered in constitutive modeling of mechanical properties of HEAs. It should be noted that any reuse of the data must adhere to legal and ethical standards., , , # Raw image of the thickness of twins under quasi-static and dynamic deformation [https://doi.org/10.5061/dryad.h70rxwdvg](https://doi.org/10.5061/dryad.h70rxwdvg) ## Description of the data and file structure We count the twin thickness by counting atomic layers from HRTEM images, thus the twin thickness can be precisely determined.  ### Files and variables #### File: raw\_images.zip **Description:** Raw images for Fig.S6 and Fig.3.
