Abstract Determination of the stacking fault energy, Y, of the solid solution strengthening superalloys with various contents of Co and W with relation to their steady-state creep rate, s was carried out by X-ray texture method. The stacking fault energy decreases with the increase of Co and W. An expression may be proposed as ε ∞ γ~m, where m=1.46.
