Single crystals of nickel containing up to 21.5at%Cr were deformed in tension at 78 to 623K. The critical resolved shear stress of alloys containing up to 9at%Cr, in the region of the athermal plateau, could be fitted to a power-law function of the Cr concentration. The work hardening parameters were examined and the temperature and strain-rate dependence of the stress at the onset of dynamic recovery was used to evaluate the stacking-fault energy as a function of Cr content. The value for Ni was 415mJ/m2.
