Využití metod SPD pro výrobu UFG materiálů

Abstract

JANKO, Tomáš. Use of SPD Methods for the Production of UFG Materials. Ostrava, 2024. Bachelor thesis. Ostrava: VSB - Technical University of Ostrava, Faculty of Mechanical Engineering.

The bachelor thesis deals with the properties of materials with ultra fine-grained structure (UFG) and with methods of severe plastic deformation (SPD), used for production of these materials. The introductory part contains a review about influence of grain size on material properties, and also individual methods of severe plastic deformation are described. Next part is dedicated to a detailed description of the ECAP and TCAP method, which is lately utilized for processing a samples in the practical part of this thesis. The practical part is then devoted to preparation of the samples and to analysis of the initial and final structure of the samples before and after processing by the TCAP method.
