Abstract
⺠We examine the creep behavior of Al-alloys with Li and rare earth element additions. ⺠These alloys exhibit threshold stresses below which no measurable creep occurs. ⺠Larger precipitate size and lattice parameter mismatch increase creep resistance. ⺠A simple parameter describes the threshold stress behavior in ternary Al-Sc-X alloys. ⺠The findings are explained by a recent model of dislocation-precipitate interactions.
