“…Thus, when one type is present, the other types generally disappear. The bands can form in single or multiple locations in the effective gauge of a test specimen [35]. The analysis of serration shapes of mild carbon steels carried out by Cuddy and Leslie has shown that only type C bands form at random locations in a specimen gauge [36].…”

The Portevin-Le Chatelier (PLC) effect manifests itself as an unstable plastic flow during tensile tests of some dilute alloys under certain regimes of strain rate and temperature. The plastic strain becomes localized in the form of bands which move along a specimen gauge in various ways as the PLC effect occurs. Because the localization of strain causes degradation of the inherent structural properties and surface quality of materials, understanding the effect is crucial for the effective use of alloys. The characteristic behaviors of localized strain bands and techniques commonly used to study the PLC effect are summarized in this review. A brief overview of experimental findings, the effect of material properties and test parameters on the PLC effect, and some discussion on the mechanisms of the effect are included. Tests for predicting the early failure of structural materials due to embrittlement induced by the PLC effect are also discussed.

“…Under the condi tions of the Savart-Masson effect, the unloading fac tor is absent; therefore, the spatial and temporal insta bility of plastic deformation can develop according to another scenario. It was stated in [11,12] that mac rolocalized deformation bands under loading at a constant rate differ significantly from the PLC bands of types А, В, and С and form another funda mental type of plastic instabilities. The morphology, dynamics, and nucleation conditions of the defor mation bands formed under the Savart-Masson conditions have still not been investigated.…”

Because of the limitation in spatial resolution, which has a typical value of 1 mm, it is difficult to obtain the displacement distribution within the band.…”
