Abstract:

Development of the precision radial forging process was continued with full-scale forging of integral blade turbine wheels. Phase III involved an evaluation of the effectiveness of precision radial forging complex reaction and impulse-type, integral blade turbine wheels on a prototype production basis. Waspaloy and Mo-0.5Ti forged preforms were used for the forging studies. Results indicated that present technology is not sufficiently advanced to produce complex turbine wheels from the higher strength superalloys and refractory alloys. The major deficiency in the process is the application of a segmented closed-die system operating under severe stress conditions created by the turbine wheel blade configurations. Author
