High Modulus Shafts Abstract High modulus turbine shafts are described as are the process parameters for producing these shafts. The shafts have a high modulus as a result of having high <111> texture in the axial direction. The shafts are produced from a nickel base material having a strengthening phase and a moderate to high stacking fault energy. A combination of hot axisymmetric deforma- tion followed by cold axisymmetric deformation produces an intense singular <111> texture and results in shaft material whose modulus is on the order of 25% greater than that of the steel materials used in the prior art.
