Residual stress distributions around indentations and scratches in polycrystalline Al2O3 and Al2O3/SiC nanocomposites measured using fluorescence probes

We report a study of the residual stress state around indentations and single point scratches in polycrystalline alumina and alumina/SiC nanocomposites using Cr3+ fluorescence piezospectroscopy. The alumina specimens displayed residual stress levels up to 550 MPa whereas the nanocomposite specimens...
