Data for: Stacking fault energy, thermal expansion behavior, and elastic coefficients of a single-crystalline CrFeNi medium-entropy alloy

In this compilation of data, we report the dilatation behavior, temperature dependence of elastic stiffness coefficients and the intrinsic stacking fault energy at room temperature of the single crystalline, equiatomic, and single-phase FCC CrFeNi medium-entropy alloy. All the data are either origin files (.opju) or excel files (.xlsx). Here is a short description of the files, which are numbered according to their order of appearance in the corresponding research article: Fig.2: Dilatation behavior between 100 and 673 K Fig.3: Temperature dependence of the elastic parameters between 100 and 673 K, including c11, c12, c44, C=(c11+c12+c44)/3, c’ = (c11-c12)/2, Anisotropy factor (A), Bulk modulus (B), shear modulus (G), Young modulus (E), Poisson's ratio (ν), normalized Cauchy pressure (c12-c44)/C and Pugh's index (B/G). Fig.4: Plots showing the separation distance between Shockley partials as a function of the angle between the dislocation line and the perfect Burgers vector. These data allow to determine the stacking fault energy of the equiatomic CrFeNi alloy.
