Summary:Title screen
The morphology of the deformation relief bicrystals of AISI 316 steel was described in terms of statistical parameters and using nonparametric roughness criteria. The presence of two large-scale levels of plastic deformation self-organization and scaling was established. Coordinated shear in bundles of parallel shear planes was the key mechanism at the mesolevel. The processes of self-organization in the dislocation substructure was the key mechanism at the microlevel. The deformation relief close to the grain boundary was investigated. Several shear systems in two grains was active at the grain boundaries. Due to this fact, it was waited inconsistency of deformation and more rough relief at the grain boundaries then into grains. However, there was not the high values of root mean square surface roughness at the grain boundaries. In addition, the scratch testing experiment showed that the grain boundary did not have a dramatic effect in this case. The connection between the statistical parameters of the surface morphology and the stages of the stress strain curve was established.
