In a number of papers serrations on the tensile curve during the Portevin-Le Chatelier (PLCh) deformation (1) (often referred to as jerky flow) were used as the feature of the phenomena from which the information about its nature may be deduced. It is noticeable however, the regardless the conditions of deformation (temperature, strain and strain rate), the amount and frequency of serrations depend on structure of material, especially grain size. It seems, therefore, necessary that the mechanical parameters of the test to be supplemented by appropriate observation of slip pattern in the material and this is the purpose of these studies.
