Recently the American Society of Mechanical Engineers (ASME) designated the Pratt & Whitney single-crystal turbine blade an historic mechanical engineering landmark. These blades, which can be found in many modern, high-performance gas turbines and larger electricity-producing turbines, are grown from a single crystal in a vacuum casting furnace from superalloys. They increase the turbine’s efficiency and individual blades’ service life, while giving unmatched resistance to

Investment cast turbine blades have been critical to many advances in jet-engine and industrial-gas engine performance — and deserve recognition.
