ABSTRACT:
Single crystal nickel base superalloys of the gamma-gamma prime type are strengthened by deforming them 2-14% at temperatures in the range 700.degree.-1100.degree. C. Yield strength will be increased typically by 25-50%, depending on the crystallographic orientation. Careful control of parameters is necessary to obtain the strengthening while avoiding recrystallization. The metal is first homogenized and provided with a fine gamma prime deformation; strain rates in the range of 10.sup.-1 cm/cm/sec or less are used.
