MEASURING RESIDUAL STRESS

VIAX-RAY DIFFRACTION HELPS

OPTIMIZE ENGINE COMPONENT

FABRICATION

Because residual stress has a significant impact on engine

component service life, understanding its cause helps optimize

fabrication processes to ensure quality. XRD is often the only

viable technique to measure residual stresses at certain failure-

critical locations.
