Process evaluation of directionally solidified Ni/sub 3/Nb reinforced eutectics in turbine blade form. Final report, 16 Mar 1974--15 Mar 1975
Technical Report

OSTI ID:7355418
The purpose of the program was to investigate the unidirectional solidification of delta (Ni3Nb) reinforced eutectic alloys in turbine blade form. The liquid metal cooling (LMC) process, served as the basic processing technique for this investigation. The major objectives of the program were to: (1) Evaluate solidification process modifications to increase the temperature gradient capability of the liquid metal cooling process, (2) Investigate the effect of solidification conditions on the microstructure and mechanical behavior of delta (Ni3Nb) reinforced eutectic alloys solidified in turbine blade form, and (3) Evaluate the solidification characteristics associated with the fabrication of (air-cooled) eutectic turbine blade airfoils.
