Abstract
AbstractIn recent years, inhomogeneous plastic deformation associated with the Portevin‐Le Châtelier (PLC) has received a renewed attention. The PLC effect, commonly called 'jerky flow' or Serrated yielding; is the result of dynamic strain ageing due to dynamic interactions between mobile dislocations, temporarily arrested at obstacles, and dissolved alloying atoms, which diffuse towards dislocations ]1[ So, the microstructure can have an important role on the PLC phenomenon and efforts to understand these mechanisms were the subject of previous researches ]2, 3[ In this work, essentially experimental, we have changed the ageing conditions in order to investigate the effects of precipitates on the jerky flow and its characteristics.
