discusses a study on measuring residual stress on mmc components by the incremental hole-drilling and x-ray diffraction methods. the modified hole-drilling method is used for measuring the macroscopic residual stress gradient in depth, and the x-ray method is used for measuring surface residual stresses. new developments have shown that the strain measured on the surface during incremental drilling can be related to the residual stress gradient finite element software has been developed for the calculation of calibration coefficients for the hole-drilling method. some special aspects of this technique, drilling system, and stress gradient will be presented. different aluminum matrices (2024, 2124, and 6061) and sic fiber proportions have been tested. the effects of heat treatment, machining, and shot-peening treatment on the residual stress distribution of these materials will be analyzed and compared
