a) There are three types of superalloys- Fe-Ni based, Ni based and Co based. These are further divided into cast and wrought. A large number of alloys have been invented and many are patented and trademarked. Reade Advanced Materials (READE) makes a "best efforts" attempt to acknowledge all trademarks. Fe-Ni based are strengthened by intermetallic compound precipitation in a matrix. Ni based superalloys is the most important class. The Co based superalloys are invariably strengthened by a combination of carbides and solid-solution hardeners.
b) A superalloy, or high-performance alloy, is an alloy that exhibits excellent mechanical strength and creep resistance at high temperatures, good surface stability, and corrosion and oxidation resistance. Superalloys typically have a matrix with an austenitic face-centered cubic crystal structure. A superalloy's base alloying element is usually nickel, cobalt, or nickel-iron. Superalloy development has relied heavily on both chemical and process innovations and has been driven primarily by the aerospace and power industries. Typical applications are in the aerospace, industrial gas turbine and marine turbine industry, e.g. for turbine blades for hot sections of jet engines.
c) Examples of superalloys are Hastelloy, Inconel, Waspaloy, Rene alloys (e.g. Rene 41, Rene 80, Rene 95, Rene 104), Haynes alloys, Incoloy, MP98T, TMS alloys, and CMSX single crystal alloys. Source: Wikipedia
