Abstract
Creation of aircraft engines of new generation demands development of prospective materials, including heat-resistant nickel single crystal superalloys for turbine rotor blades.
New trend for doping heat resisting alloys is being developed in JSC “NPO SATURN”. Mathematical modeling coupled with numerical optimization is used to find new compositions of alloys. The paper presents the results of developing two nickel superalloys, providing high temperature long term strength at the level of up-to-date materials. One of them doesn’t include ruthenium, so the cost of its blend is app. 450 USD/kg, which is app. 2 times less than known analogues. Another doesn’t include both rhenium and ruthenium, its blend costs 130…150 USD/kg, being 6…8 times cheaper as compared to materials having comparable performance.
