摘要：
Recent achievement of the microstructure control of directional single crystal superalloy has been reported. For example, a wide chord blade with single crystal microstructure can be obtained and the column microstructure at profile can be obtained. A new technology can raise the temperature capability of superalloy and life of gas turbine engine.
