Abstract

In order to clarify the additive effect of different solute elements on the solute-atmosphere drag stress of dislocations, solution-strengthened Al-Mg, Al-Cu and Al-Mg-Cu alloys were creep-tested at 723 K under stresses ranging from 3 to 12 MPa. The effective stress, internal stress and dislocation mobility were measured during deformation by the stress change technique. It is found that a relation holds in common for these alloys. From this relation, it is concluded that the effective stress for the solute-atmosphere drag in the tertiary alloys is simply given by the sum of solution hardening due to Mg and Cu atoms.
