Abstract

Statistics of damage of steam turbine disks operating in the zone of phase transformation is analyzed and it is inferred that it is possible and expedient to determine group lives of rotor parts experiencing the action of permanent and objective negative factors. Statistics of damage in the form of circular cracks in low-temperature rotors of steam turbines of various types is presented.

Keywords
