Transformace dynamické odolnosti nerezových ocelí vlivem strukturní nehomogenity
 Dobrovolný, Pavel
This diploma thesis: Transformation of the dynamic resistance of stainless steels due to structural inhomogeneity deals with the effects of corrosive damage on fatigue properties of stainless steels. The theoretical part deals with general principles of creation and chemical reactions, the factors affecting their speed, as well as, fatigue properties of materials (formation of cracks, stages of high cycles fatigue, fatigue slip zone etc.) and description of the method of non destructive testing the acoustic emission. The practical part describes executed experiment which focuses on comparing the results of fatigue tests between the standards and thermal and corrosion exposed samples. The actual measurements supplement microscopic images of the fracture surfaces and the records acoustic emission during measurements of some samples.

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.
