MEASUREMENT AND EFFECT OF RESIDUAL STRESSES ON TURBINE COMPONENTS

Through the application of blind hole drilling techniques, the residual stresses in turbine components were determined. The equations used reduce the measured variance in strains to calculate residual stresses for both the on-center and off-center hole drilling procedure. Inherent residual stresses were observed in two turbine alloys, Ti-6A 1-2Sn-4Zr-2Mo and Waspaloy. Residual stresses were found to be different in the forged turbine component and in the fatigue-crack growth test specimens machined from the component. Residual stresses of a material appear to be affected by its microstructure and crystallographic texture.
