METHOD OF PROCESSING RODS FROM HEAT-RESISTANT STEELS AND ALLOYS TO PRODUCE COMPRESSOR BLADES FOR A GAS TURBINE ENGINE

Inventors

1. A method for processing rods made of heat-resistant steels and alloys to produce compressor blades for a gas turbine engine, including incoming inspection of the rod's macrostructure for the longitudinal direction of the fiber therein and the accumulated value of at least 0.7 of the total relative deformation obtained during the process of preliminary hot processing of the ingot into a rod, heat treatment of the rod in accordance with the requirements of the technical specifications for the blades, and subsequent mechanical and finishing treatments to obtain the final dimensions of the part.
2. The method according to paragraph 1, characterized in that when processing a rod made of aging heat-resistant steels and alloys, it is subjected to hardening before mechanical processing, and aging is carried out before finishing processing.
3. The method according to paragraph 1, characterized in that aging before finishing treatment is carried out in vacuum furnaces.
