This paper reviews the current situation and the history of development of cast turbine blades of Chinese aircraft engines for nearly three decades since 1956 and sums up the cast high-temperature alloys and casting methods which were provided by the materials and casting scientific and technical personnel during this period which have met the demands of aircraft engines. Remarkable successes have been made in many fields such as cast rotor blades, ceramic cores for hollow blades, research into dispersion-strengthened alloys, and computer-based quality control, etc. With a view to future development of high performance engines this paper proposes research on ceramic and refractory materials to meet the following requirement 1 increased operating temperature 2 enhanced surface stability 3 superior mechanical properties.
