Experimental and computer - assisted modeling of plastic deformation of zircon - based alloys during production of metal products for the needs of the atomic and other branches of industry

In this work, a task was set to study the rheological properties of zircon-based alloys with a modified chemical composition of the Zr - Nb and Zr - Nb - Sn systems with respect to the conditions of different processes of pressure metal treatment during manufacturing of pipes and rods. For this purpose, complex plastometric tests of new grades of alloys were carried out to obtain experimental data on the deformation resistance value σp and maximum permissible plasticity Λр of these materials. The tests were carried out on a modern plastometric apparatus in a wide range of thermal mechanical conditions of deformation according to different forms of loading. On the basis of the experimental data on the mechanical properties of the materials under study, pressure metal treatment processes were developed using the Forge 2008 computer modeling software package.
