Residual stresses of surface nanocrystalline material by moire interferometry and hole-drilling method

The surface of metal structure can be transmitted into nanocrystalline by means of supersonic shot-peening. Residual stresses of stainless steel 316L caused by surface nanocrystalline were studied by a combined method of moire interferometry and hole-drilling. Residual stresses of different specimens with nanocrystalline layer and plastic deformation layer removed were also studied. The experimental result show that nanocrystalline layer and plastic deformation layer are main parts to remain high residual stresses, and to enhance the mechanic behavior of materials.
