This paper describes a study on a method of X-ray stress measurement for the nondestructive determination of the gradient of macro- and micro-residual stress components in the surface layer of composite materials. The theory is explained in the first part of the present paper. An experiment on the application of the present method to a two-phase stainless steel prepared by down-cut grinding is described in the second part. The stress gradients of phase, macro- and microstresses in both α-and γ-phases were evaluated by means of the present method under the assumption of linear stress gradient. The theory was introduced under consideration of the effects of finite thickness and a nonlinear stress gradient of a type of polynomial function in order to analyze composite coatings as well as materials with a nonlinear stress gradient.
