Isolation and testing of new single crystal superalloys using alloys-by-design method
- Abstract:
- Three new single crystal superalloys are isolated using theory-based computational modelling approaches, termed alloys-by-design methods. They are (i) an oxidation-resistant low Re-containing alloy with balanced properties, intended for general-purpose gas turbine applications; (ii) an alloy containing 5.6 wt% Re and 2.6 wt% Ru suitable for high performance jet engine applications, when creep resistance needs to be maximised without oxidation performance being excessively compromised and (iii) a cheap, corrosion-resistant alloy for power generation applications designed with ease-of-processing in mind. The new alloys have been manufactured using investment casting techniques, and their creep and oxidation behaviour evaluated. The robustness of the so-called alloys-by-design methods is demonstrated, although the predictions for microstructural stability need to be improved.
