In metals of low stacking fault energy such as copper,a-brass and austenitic stainless steel,climb is difficult,and little recovery of the dislocation structure normally occurs prior to recrystallization. In metals of high stacking fault energy such as aluminium and a-iron,climb is rapid,and significant recovery may occur. ▣ Solutes may influence recovery by their effect on the stacking fault energy, by pinning dislocations,or by affecting the concentration and mobility of vacancies.Solute pinning of dislocations will both inhibit dynamic recovery, resulting in a higher stored energy than for a solute-free material,and also inhibit static recovery.
