The Influence of Intensive Plastic Deformation on Iron-Based Materials by Free Precipitation

Abstract

The development of many branches of modern production is inextricably linked with the development of new materials with a certain complex of mechanical, physio-chemical and technological properties. One of the effective ways to obtain materials with clearly defined properties is powder metallurgy. Materials obtained by pressing the powder usually have a high residual porosity. In order to improve their mechanical properties, we suggest using free sludge. We experimentally investigated various methods of intense plastic deformation and measured the hardness and strength of the obtained samples. We believe that our results show that free sludge can be used for reducing porosity levels in powder materials on an industrial scale.

Research of Geometric and Information Models for Awning Structures

“…Membrane structures are not only an effective accent of any architectural exhibition, but also a convenient tool for creating aesthetically pleasing compositions. When modeling the surface membrane, it is important that the system, which consists of a shell and a rigid frame is a system with distribution parameters [6]. The main problem of mathematical modeling is that with a small change in shape, significant changes in load can occur at individual points.…”
