A unified description of solid solution creep strengthening in Al–Mg alloys

► Mobile dislocation density explains apparent n variation. ► Strain rate for dislocation climb is five times slower than for dislocation glide. ► Self-diffusion of aluminum is the controlling process for creep of Al–1%Mg. It is proposed that the creep strengthening of aluminum due to the addition o...
