Abstract

A model describing the interplay of precipitation and dynamic strain ageing is proposed. Both homogeneous and heterogeneous precipitation is considered. It is shown that as a result of precipitation in concentrated solid solutions the critical strains for the occurrence of the Portevin-Le Chatelier effect should exhibit an "inverse" behaviour with temperature and strain rate as compared to the behaviour observed in dilute solid solutions.
