Popis:	The paper considers the irreversible deformation of steam turbine rotors due to the circumferential non-uniformity of the material mechanical properties based on the numerical analysis of their three-dimensional stress-strain state. It is shown that this non-uniformity can be one of the causes for the occurrence and development of progressive creep deflection of high-temperature rotors that have been in long-term operation and also their bending in case of excess of the rated rotational speed.
