Creep behavior of solid solution alloys are reasonably explained by concepts of the "internal and effective stress of high temperature deformation". The internal stress is considered to be formed by dislocations, and long range stress filed should also be formed by dislocations in interior of alloys. Thus, residual stresses should be measurable by different methods. In this paper, measurements of the residual stresses in crept solid solutions by 2D-XRD method have been attempted, and the residual stresses are compared with so-called the "internal stress of high temperature deformation" measured by strain-dip stress-transient test. Although, components of stress tensor depend both on the deformation condition and position of specimen, the mean value of the maximum principal stress are smaller than the applied stress and show the same trend of the applied stress dependence with the mean internal stress measured by strain-dip stress-transient test. Importance of further considerations of the origin of so-called internal stresses is suggested.
