Superalloys II
Superalloys are those alloys based on Group VIIIA-base elements developed for elevated temperature service in virtue of their combination of mechanical strength with surface stability in such corrosive environments as those of aircraft and industrial gas turbines, coal conversion plants, etc. An updated account is presently given of the genesis and character of superalloys; superalloys' impact on gas turbine design; precipitation- and dispersion-strengthening, and precipitation-hardening; representative Ni-, Co-, and Ni-Fe-base alloys; directionally solidified superalloys; phase composition prediction, mechanical behavior, and fatigue; high temperature oxidation, hot corrosion, and protective coatings; investment-cast, wrought, and P/M alloys; and prospective competition for superalloys from nonmetallic materials.
