Investigation of recrystallization in an Al-0.3 Mg alloy by the method of internal friction

The Al-0.3 at % Mg alloy subjected to deformation by rolling (ɛ = 90%) at room temperature has been investigated by the method of internal friction. The influence of deformation and subsequent recrystallization on the temperature dependence of the amplitude-dependent and amplitude-independent internal friction has been determined. Effects of anelasticity due to recrystallization and grain-boundary relaxation have been revealed and investigated; parameters of corresponding peaks of internal friction have been determined and discussed. When studying the kinetics of recrystallization, the high sensitivity and selectivity of the procedure used have been shown.
