Investigations for the development of a SLZhS-32 BR promising rhenium-free heat-resistant nickel alloy for single-crystal turbine blades are carried out. The chemical composition of the experimental promising alloy is calculated and substantiated, and a pilot batch (10 kg) of the alloy is smelted. According to analytical results of the investigation, the long-term strength of the developed alloy is 248 MPa at 1000°C and 100 h.
