| Abstract: | Recent achievements of microstructure central of directionally single crystal superalloy is reported in this paper. For example, wide chord blade with single crystal microstructure can be obtained by high speed directional solidification, and combined blades with single crystal at leading and trailing edge and columnal microstructure at profile can be obtained. These new technologies can raise temperature capability of superalloy and life of gas turbine engine. |
