Abstract The stress exponent of steady-state creep at 300°C for Al-1.77, 4.20 and 7.72 at% Mg alloys varies from 3.37 to 3.98 with increasing Mg content when determined using the applied stress, σ. However the stress exponent remains constant at ≈3 when calculated using the effective stress, σe. The back - or friction - stress, σ0, determined from stress-dip tests increased significantly with increasing σ.
