Abstract:
A study is made of how the mechanism of plastic deformation of polycrystalline low-carbon steel is a ffected by large-scale interface in the form of long localized regions of remelted material extending in the transverse direction. It is shown theoretically and experimentally that oscillating stress mesoconcentrators develop in the neighborhood of such interfaces and that relaxation of these concentrators results in the formation of periodic mesoband structures in deformable polycrystals.
