Appreciate the Significance of Single-Crystal Turbine Blades

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

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
