ABSTRACT:
A turbine rotor is formed from a turbine disk having a rim with a circumferential direction, and a plurality of turbine blade segments each fixed to the turbine disk around a circumference of the rim of the turbine disk. The turbine blade segments are oriented such that the elastic modulus of the turbine blade segments parallel to the circumferential direction is less than that of the rim of the turbine disk parallel to the circumferential direction. This arrangement is preferably achieved using single crystal turbine blade segments made of an an alloy having a cubic crystal structure, such as a nickel-based superalloy, with a <010> direction oriented radially and a <001> direction oriented circumferentially.
