Abstract Strain transients following stress decrements were investigated during the creep of an Al-7.72at.%Mg alloy at 300°C. After an instantaneous reverse strain the transients for small stress reductions consisted of two regions of constant strain rate (stages I and III) separated by a fairly short transition or breakaway region (stage II). The instantaneous reverse strain was always greater than that expected from purely elastic behaviour. The transients in stages I and III are compared with previous data for Zr-1wt.%Nb and copper and are rationalized in terms of a recovery creep theory in which either of two separate recovery processes may be rate controlling.
