The reason that vast numbers of people fly these days is because flying is relatively inexpensive. Once the aircraft has been paid for, the big operating cost for airlines is the cost of the fuel, and fuel efficiency has increased by over 45% since the 1940s.

Understanding Superalloy Metallurgy
2002Abstract This chapter describes the metallurgy of superalloys and the extent to which it can be controlled. It discusses the alloying elements, crystal structures, and processing sequences associated with more than a dozen phases that largely determine the characteristics of superalloys, including their properties, behaviors, and ...

Polycrystalline Cast Superalloys
1990Abstract The initial cast superalloy developments in the United States centered on cobalt-base materials. Nickel-base and nickel-iron-base superalloys owe their high-temperature strength potential to their gamma prime content. For polycrystalline superalloy components, high-temperature strength is affected by the condition of the grain ...

Melting of superalloys is the initial, and perhaps most important, step in the production of materials used in critical high-temperature applications. Increasing demand for high-quality superalloys with specific characteristics has resulted in various combinations of primary, melting, refining, and secondary remelting operations.
