Abstract

The paper presents the analysis of structural research, micro-hardness and mechanical properties of the base material which is steel 904 L and joints made with CO2 laser beam and TIG method. The analysis of the equilibrium system created in the Thermo-Calc programme based on chemical composition shows a dominancy of austenite with of Feα additions, phase σ, P and Laves' and M23C6 and Cr9Mo21Ni20 carbides. EBSD (Electron backscatter diffraction) research done by using electron scanning microscope confirmed the presence of pure austenite.
