Characterization of the spatiotemporal behavior of the PLC bands in austenitic steel during deformation at elevated temperature
Source abstract
Abstract
Abstract The digital image correlation technique was used in situ during tensile testing to investigate the behavior of the Portevin–Le Chatelier (PLC) bands in a Fe–18Cr–8Ni–2.8Cu austenitic steel at a temperature of 680 °C. Effect of the strain on characteristics of the PLC bands, namely velocity, its intensity and the distance propagated by the bands was studied. New data of the spatiotemporal behavior of the PLC bands at elevated temperature were obtained. The PLC bands propagate continuously along the entire gauge length of the sample. The cause for such behavior of the PLC bands was discussed.
