Abstract

The results of experimental studies of short-term strength, long-term strength, multi-cycle fatigue and low-cycle fatigue of the castable corrosion-resistant nickel-based superalloy VZhL23 for turbine blades of GTI and GTE are presented.

Comparative analysis of the obtained values of long-term strength, multi-cycle fatigue and low-cycle fatigue of VZhL23 with the most heat-resistant foreign alloy IN-792 is carried out. It has been established that according to the set of mechanical properties VZhL23 is not inferior to IN-792.
