Abstract: A method of monitoring the residual stress in surface and near surface regions of a component includes identifying predetermined locations on the surface of a component that are expected to experience high stress during normal operating conditions of the component. Marker particles are introduced into the component during additive manufacture of the component at the predetermined locations. Then, the residual stress of the component is measured at a location corresponding with the marker material using x-ray techniques.

Abstract: One embodiment includes a fuel injector. The fuel injector assembly comprises a conduit for conveying fuel from a fuel inlet to a nozzle. The conduit is located in a support, with the conduit, the nozzle, and the support being a single unitary piece. A thermally compliant feature is located at the nozzle which allows the fuel injector to adjust for differential thermal expansion.
