Description

In this compilation of data, we unconver reasons for the superior annealing-induced hardening behavior of the Cr27.3Co33.3Ni33.3Mo6 (Mo-6) and MP35N alloys compared to the equiatomic CrCoNi (Mo-0) medium-entropy alloy. All the data are ORIGIN and EXCEL files (.opj and .xlsx). Here is a short description of the origin files, which are numbered according to their order of appearence in the corresponding research article and supplementary materials: Fig01+S1+S2: Vickers microhardness of Mo-6 after two-step hardening. Fig02: Tensile responses of Mo-0 and Mo-6 MEAs. Fig06: 1D-composition profiles (crossing a GB and TBs) and frequency distribution of the elements extracted from APT experiments. Fig07: The plot shows the temperature dependence of Vickers microhardness over the whole longitudinal-section of the Mo-0 and Mo-6 MEAs, from which the recrystallization temperature can be determined. Fig08: Effect of plastic deformation and post-deformation condition (as-swaged and post-deformation annealed for 4 h at 773 or 923 K) on the yield stress and ultimate tensile strength (UTS) in Mo-0 and Mo-6 MEAs. Fig10: Relative strengthening related to post-deformation annealing in the Mo-0 and Mo-6 MEAs. Fig11: Ashby map showing the ultimate tensile strength as a function of elongation to fracture of CrCoNi-based MEAs and HEAs. FigS8+S9: XRD patterns of Mo-6 and MP35N.
