a Lattice and elastic constants of VNbMoTaW and TiZrNbHfTa with ideally random configuration. b Square root of the MSAD values of each constitutive element, and the average of all elements, normalized by the Burgers vector (the error bars represent standard deviations). Inserted atomic images are typical examples of the relaxed configuration (See Supplementary Fig. 4). c, d Typical configuration of a screw dislocation dipole in TiZrNbHfTa (c) and VNbMoTaW (d), where the dislocation core is visualized using the differential displacement vector. e Frequency distribution of the core energy normalized by the energy calculated by the elasticity theory for 135 dipole configurations in TiZrNbHfTa and VNbMoTaW (note the break in the energy scale, horizontal axis).
