A method, based on Monte Carlo constrained optimization, has been devised for designing superalloys. The Larson-Miller parameter at 100 MPa is maximized subject to M (d) (total) < 0.99, M (d) (gamma) < 0.94 and, for superalloys with at.%Mo + at.%W > 4.32, Mo/(Mo + W) < 0.27. The maximum density of the alloy can be specified as well as the composition range of any constituent element. The design of a patented alloy is illustrated and the possibility of designing new low density, corrosion resistant superalloys is discussed.
