Studium mechanických vlastností svarových spojů oceli P92

Abstract

This master thesis deals with study of modified 9 – 12 % Cr steels. The introduction describes the mechanical properties and microstructure of modified steels with a focus on steel P92. The next part of thesis is focused on welded joints and the weldability of modified martensitic steels. In the experimental part of the master thesis specimens were welded and consequently heat treated. The welded joints were examined by destructive and non-destructive tests. The conclusion includes the evaluation of achieved results of destructive and non-destructive tests of welded joints.
