Abstract The minimum grain size determined by the resolution of X-ray texture analysis and the maximum grain size for linear stress measurement curve were calculated for the quasi-isotropic polycrystal. The results show that in certain grain size range, to which texture analysis are insensitive, stress measurement curve can still be nonlinear. The critical grain sizes for iron material are given to show that for certain grain sizes, when d-sin~2Ψ curve is nonlinear, the effect of grain size should be taken into consideration together with that of texture.
