Models have been developed and used as tools to design a new ‘made to measure’ nickel base superalloy for power plant applications. In Part 1 Gaussian processes were used to model the mechanical properties of superalloys, and have been used as a basis for the design of a new Ni-Cr-W-Al-Ti-Fe-Si-C-B superalloy with desirable properties. In this part, an attempt has been made to design against the formation of undesirable phases, and to calculate the solidification range, forging window and heat treatment, using phase diagram calculations. The potential for chemical segregation has also been estimated following Scheil's assumptions, and remains acceptable.
