guide ray
1.A low carbon martensite stainless steel 0Cr13Ni4Mo normalized at 1000℃ and tempered at 600℃, used in the guide stream assemblies of water turbine, was treated with shot peening. The depth distributions of microhardness, half-width value of X-ray diffraction profiles and yield strength in the shot-peening affected layer were measured. Correspondingly, the depth distributions of microstructure parameters, such as subgrain size, microstrain and dislocation density, in this layer were calculated.
