This diploma thesis deals with the analysis of mechanical properties of bimetallic materials with clad layer of Inconel. In the theoretical part of the work there is an analysis of the investigated bimetallic material. The following is a description of mechanical tests and methods for evaluating the integrity of the surface, which were used to determine the properties of bimetallic material. The experimental part focuses on individual tests of mechanical properties of the material. For each test, the procedure for the production of test specimens, a description of the test equipment, the performance of the tests, the evaluation of the data obtained and finally, the evaluation of the results obtained are given.

The thesis aim is an evaluation of achieved results coming from the analysis of pipe bend 180° for the critical bending / bend 1D and supercritical bending / bend 0,7D. The theoretical part is focused on material property of a bimetallic pipe and on methods applied to work out the analysis. The definition of critical points at a considered segment and possible defects arisen while bending is embodied in the thesis. The practical part of the thesis is based on presenting dimensional and proportional analysis based on using optical microscopes and 3D scanner GOM ATOS. The material analysis was aimed at macrostructure as well as microstructure of the bimetallic pipe material, at chemical composition and at the hardness when low-loaded. The analysis achieved results are assessed at the end of the thesis.
