Description

In this compilation of data, we show how the stacking fault energy and grain size affect the critical twinning stress in CrxMn20Fe20Co20Ni40-x high-entropy alloys. The raw data and analysis can be found in the following folders, numbered according to their appearance in the corresponding research article: (1) Fig.01-02_tensile_tests_20µm.opju: In this origin file, you find the tensile data at 77 and 293 K obtained on the Cr14Mn20Fe20Co20Ni26 and Cr24Mn20Fe20Co20Ni16 (in at.%) alloys with a mean grain size of about 20 µm. Within the file you will find the tensile curves used for Figs. 1 and 2 of the corresponding research article. (2) Fig.03-05_tensile-tests_60µm.opju: In this origin file, you find the tensile data at 77 and 293 K obtained on the Cr14Mn20Fe20Co20Ni26 and Cr26Mn20Fe20Co20Ni14 (in at.%) alloys with a mean grain size of about 60 µm. Within the file you will find the tensile curves used for Figs. 3 and 5 of the corresponding research article. (3) Fig.04-06_tensile-tests_250µm.opju: In this origin file, you find the tensile data at 77 and 293 K obtained on the Cr14Mn20Fe20Co20Ni26 and Cr26Mn20Fe20Co20Ni14 (in at.%) alloys with a mean grain size of about 250 µm. Within the file you will find the tensile curves used for Figs. 4 and 6 of the corresponding research article. (4) Fig.07_Deformation_twin_thickness.opju: Here you will find the origin file, which shows how the deformation twin thickness depends on applied stress, grain size, and Cr-concentration (and thus stacking fault energy).
