Sažetak
The rotors of steam turbines belong to the extremely loaded parts of turbo generators due to various mechanical and thermal influences during their operation. The following paper presents the results of the analysis of failure causes of the rotor shaft of a steam turbine with the power of 6,43 MW, which occurred after approximately one year of operation. The analysis was performed on the basis of the analysis of the chemical composition and microstructure of the material, the mechanical properties of the material under static and fatigue loading, as well as operational loading of the critical location of the shaft, using numerical and analytical methods. The conclusions about the possible causes of the shaft failure were drawn on the basis of the results obtained.
