Abstract
A digital image correlation technique combined with in situ neutron diffraction was used for the first time to investigate the Portevin–Le–Chatelier (PLC) behavior in an Fe–24Ni–0.3C steel. Propagating type A + B PLC bands observed in the early stage of plastic deformation changed to the non-propagating type C bands due to the occurrence of deformation-induced martensitic transformation.
