Abstract
After the completion of HPT engine ДЦ59Л, ДЖ59 designed service life the set of blades has been analyzed in order to determine its maintainability. Mechanical properties, micro-and fine structure of blades in an initial conditions and after the recovery high-heat treatment have been identified. It is established that this set of blades is repairable, the recovery high-heat treatment improves mechanical properties of blades and stabilizes the structure of their alloy.
