Abstract
A model describing the interplay of precipitation and dynamic strain a geing is proposed. Both homogeneous and heterogeneous precipitation is considered. It is shown that as a result of precipitation in concentr ated solid solutions the critical strains for the occurrence of the Po rtevin-Le Chatelier effect should exhibit an ''inverse'' behaviour wit h temperature and strain rate as compared to the behaviour observed in dilute solid solutions.
