Summary

The subject belongs to a group of branch courses, which builds on knowledge student of mathematics and mechanics. Among the selected technology training volume of UFG and nano materials (BNM) and the promising methods of treatment include special forming technology. In the course are discussing the theoretical fundamental forming processes BNM, BNM properties and methods of their analysis, modeling the process of forming BNM, all with a goal on application processing BNM forming. In the first part, students are informed on models of plastic deformation in ultra-fine grained materials. The most developed technologies of ultra-fine grained (nano) materials are analyzed in the next parts. Following the geometry effect of the forming tools on the forming process and tools is analyzed and influence of grain refinement with ECAP and DRECE technology to achieve the necessary parameters. There are the most scientifically and industrially developed methods. Results of grain refinement and mechanical properties are experimentally verified and evaluated of selected materials.
