SUPERALLOYS FOR TURBINES
Among the many different technologies that have made possible the development and oper- ation of gas turbines at very high temperatures, superalloys stand at the forefront.
The alloys used in the manufacture of jet engines and industrial and marine gas turbines repre- sent the leading edge in materials, and in turn these engines have been the primary driving force for the development of superalloys.
Rocket engines, nuclear reactors, submarines, steam power plants, and space vehicles also extensively use superalloys.
The remaining 30 percent gain in inlet temperature is derived from improved superalloys and casting processes.
