Abstract

The paper presents the results of experimental studies of the dependence of melting temperature, phase composition, structure, and heat resistance (at 1100°C in the air) of the HTN-62 alloy on additional doping with molybdenum, titanium, hafnium, tantalum, cerium, and rhenium. Based on the experimental data obtained, the most promising doping elements providing the maximum heat resistance of the alloy were identified. The results of the study are a certain stage for further improving the heat resistance of alloys, ensuring their strength and performance under extreme operating conditions. The modi¬fied alloy can be successfully used to coat the contact surfaces of the upper shroud of turbine blades and aircraft engines.
