The influence of temperature on the dynamic and static characteristics
of unstable plastic flow due to the Portevin-Le Chatelier effect is i
nvestigated experimentally and by numerical modeling. It is concluded
that the distinctive features of the complex macroscopic behavior of t
he plastic instability are determined by collective processes associat
ed with the long-range interaction of dislocations and lead to dynamic
effects of mesocopic scale, (C) 1998 American Institute of Physics. [
