Fourth International Workshop on Nondestructive Testing and Computer Simulations in Science and Engineering
Residual stress profiles in speed gears for automotive vehicles were determined. The profiles were: measured at the root between two teeth of the gears by x-ray diffraction. The gears were cemented, quenched and annealed. After these heat treatments, compressive residual stresses were: introduced by shot-peening. The profiles of stress distribution indicate the maximum of comlpressive residual stress (-950 MPa) at a depth of 0.05 mm. The stresses decrease to zero at a depth of 0.25 mm.
