Abstract: A cast nickel-iron-base alloy component having by weight about 12.0% to about 16.5% Cr, about 1.0% to about 2.0% Al, about 2.0% to about 3.0% Ti, about 2.0% to about 3.0% W, about 3.0 to about 5.0% Mo, up to about 0.1% Nb, up to about 0.2% Mn, up to about 0.1% Si, about 0.05% to about 0.10% C, about 0.003 to about 0.010% B, about 35% to about 37% Fe, and balance essentially Ni and inevitable impurities. The nickel-iron-base alloy component has a creep rupture life greater than about 1000 hours at about 25 ksi to about 30 ksi at about 1400° F. A method for forming the cast nickel-iron-base alloy component is also disclosed.

Abstract: A total cost of ownership model is input by a series of graphical user interface pages. The model may include identification of specific tasks, including sub-activities and activities. Data sets are generated by progressively inputting costs, time, labor rates, and other key information for the various activities and sub-activities. Total cost of ownership calculations are made and the data may be rapidly and interactively displayed in graphical formats, tabulated formats, flow charts, and so forth. The tool permits the evaluation of both existing and alternative or solution scenarios for equipment ownership and servicing.
