Metodika vyhodnocování výsledků creepových zkoušek a její praktická aplikace na moderní žárupevné oceli

Abstract

The submitted bachelor thesis deals with the methods evaluating the results of creep tests. The thesis is divided into two parts. The theoretical part is a literature review, dealing with the creep, creep tests, the most important creep characteristics, including methods for their evaluation. In the practical part, selected parametric equations are used to perform the calculation of creep rupture strength limit based on the results of creep tests of advanced heat resisting steel P 91. There will also be shown how the scope of creep data, particularly the maximum length of their duration, may affect the prediction of long-term creep characteristics.
