Abstract
A thermomechanical treatment for producing useful microstructures in the nickel base superalloys is described. The process is applied to material which has been placed in a condition of super-plasticity, and utilizes isothermal hot deformation under conditions which produce a uniform dislocation density and a resultant propensity for abnormal grain growth. The material is then recrystallized in a thermal gradient to produce a final structure consisting of elongated grains.
