Project Description

QuesTek Innovations will computationally design a highly castable single crystal (SX) nickel-based super alloy that can be cast as large Industrial Gas Turbine (IGT) blade components, provide hot corrosion resistance, and provide superior creep performance comparable to state-of-the-art SX aero-turbine blades.

Project Benefits

IGTs operating at higher temperatures, enabled by new high yield SX castings, can operate at higher efficiency and thus reduce electricity-generation costs and CO2 emissions. The high yield of the new SX alloys will accelerate their adoption by the IGT community, and their enhanced temperature capability will allow hydrogen-fueled turbines and ultra-high temperature steam turbines to be developed, thus bringing the vision of zero-emission fossil-fuel power plants a step closer to realization.
