摘要：
A method of multistage pack rolling (MPR) is investigated, which yields an ultrafine-grained (up to nanocrystalline) structure in ultralow-carbon IF steels used in the production of automobile steel sheets. The results of estimating the effect of temperature and the number of passes in MPR on structure and mechanical properties are given. The effect of MPR on technological plasticity is determined using the normal plastic anisotropy index (the Lankford coefficient).
