Mechanické a únavové vlastnosti 3D tištěných materiálů po HIP zpracování

Abstract

This diploma thesis examines the microstructural, mechanical and fatigue properties of the AISI 316 steel that was produced by additive manufacturing and that has undergone the HIP process. The goal of this thesis is to specify how the HIP process influences the mechanical and microstructural properties of test samples, which were produced by 3D printing using the SLM technology. The theoretical part of this thesis focuses on the additive manufacturing of metals, the microstructural, mechanical, and fatigue characteristics of austenitic stainless metals and how the HIP process influences them. The experimental part of this work focuses on the mechanical, fatigue, and structural properties of the samples that have been produced by additive manufacturing and that have undergone the HIP process. The results are then compared with the results of the samples that have been also manufacted by 3D printing, but have not undergone the HIP process. The results are also compared with the properties of AISI 316 steel, which were manufactured by a conventional method. The obtained results are summarized and evaluated in the conclusion chapter.
