Abstract
The influence of temperature on the dynamic and static characteristics of unstable plastic flow due to the Portevin-Le Châtelier effect is investigated experimentally and by numerical modeling. It is concluded that the distinctive features of the complex macroscopic behavior of the plastic instability are determined by collective processes associated with the long-range interaction of dislocations and lead to dynamic effects of mesocopic scale.
