Abstract
Residual stress in an engineering component induced from processing is pervasive and can impact the component’s performance significantly. There are numerous destructive and non-destructive techniques that are available to determine the residual stresses in a component. In this work, an interference fit sample was manufactured from a titanium alloy. The sample was equipped with a set of strain gauges to measure the strains induced by the interference process used for sample assembly. Energy dispersive diffraction experiment using synchrotron radiation was conducted to measure the lattice strains in the interference fit sample. Hole drilling measurements were also conducted on the sample. The non-destructive X-ray result is compared with strain gauge measurements, and found to be in good agreement when appropriately averaged.
