Abstract
Condition of the material of gas turbine engine blades after long-term service was studied and their repairability was determined. Parameters were developed for high-temperature heat treatment of alloy KhN65VMTYu (EI893) to extend the service life of product.
 
 
Keywords: blades, reduction heat treatment, microstructure, physical-mechanical properties, extension of service life
