Abstract：The residual stresses induced by an indentation were studied in 5% SiC/Al2O3 nanocomposite using fluorescence spectroscopy in this work. It was found that within the indentation and the region of about 10 μm outside the impression, the broadening of the R-lines is obvious, and that the compression shift is a strong function of the distance from the indentation centre. From the observed frequency shifts, the hydrostatic stresses in regions sampled in the indentation, and in the complex stress field surrounding it were measured. The same variation regularity of stresses exists along the diagonal direction and the side vertical bisector direction. The symmetry of the residual stress field around the indentation was also found.
