Optimizing the production process chamber 80C
List, Jaroslav ; Zemčík, Oskar (referee) ; Dvořák, Jaromír (advisor)
The aim of this bachelor thesis is to suggest optimisations of the production process of chamber 80C at various stages of production and assess their applicability. The main emphasis is on reducing production costs. In the first chapter we analyze specifications and requirments of the customer. There is a suggested optimisation of procedures. In the theoretical part of thesis we analyze materiál, welding methods and production technologies used to manufacture parts of the working chamber. In the practical part we assess the applicability of possible methods of welding and cutting. We will choose parts of the weldment suitable for optimization and dedicate the optimisation suggested in the first chapter. In the conclusion we assess the optimisation suggestions from the economic point of view.

Změna vlastností nerezových ocelí v agresivním prostředí
Dobrovolný, Pavel
The bachelor thesis on the topic: Changing the properties of stainless steels in aggressive environments examines the influence of heat exposure and aggressive environment on mechanical properties of stainless steels. The theoretical part describes the principle of corrosion, possibility of spreading corrosion, selected corrosive environments, types of corrosion and the factors that affect the intergranular corrosion of stainless steels. The practical part deals with verification experiment that consists in finding the influence of corrosion degradation on mechanical properties of stainless steels. Etalons and corrosion exposed samples from various grades of stainless steels were subjected to tensile test. The evaluation experiment was done by comparing the measured values of tensile test. Practical measurements complement metallographic images.
