Velocity as a function of stress for a, edge dislocations and b, screw dislocations in the RHEA and in pure Mo and Nb at temperatures of T =  300 and 2000 K. Velocity as a function of stress for edge and screw dislocations in the RHEA and in pure Mo at temperatures of c, 300 K and d, 2000 K. For all of the results the symbols are simulation data and the solid lines are guides to the eye, connecting results for a given dislocation character (edge or screw) and given temperature.
