Abstract
The dependence of yield stress of Al-Li binary alloys on deformation t emperature is studied at temperatures ranged between 0.5 and 295 K. Th e dependence is shown to become very weak during the ageing of the all oys. It may be assumed that the temperature dependence is resulted fro m the superposition of interaction mechanisms of dislocations with imp urity atoms and coherent ordered delta'-precipitates.
