Determination of the elastic constants for the residual stresses calculation from the X-ray method measurement results
A task of determination of elastic constants used for calculating the magnitude of residual stress measured by X-ray method has been evaluated for nickel based super alloys. Values of elastic response and X-ray elastic constants were calculated by using experimental data obtained by testing specimens with monocrystalline structure of three axial orientations [001], [011], [111]. Testing was done for uniaxial stretching with determination of elastic module at a temperature of 20C.
