Abstract Scope |
Additive manufacturing can produce complex and lightweight structures with a high level of flexibility and minimal waste. However, the thermal history of the additively manufactured (AM) components can result in the development of unwanted and, frequently, detrimental residual stresses. Establishing the ability to predict and control residual stresses in AM parts could lead to the design of beneficial residual stresses, which could improve the resultant properties. Various strategies to mitigate and/or control the residual stresses in AM components have been attempted. For instance, building the component on a mesh substructure changes both the path for heat to escape the component and the mechanical constraints on the component. In this work, we use high-energy X-ray diffraction to evaluate residual stresses in AM’ed bridge shape components made from Ti-5553, built directly on a solid substrate and with substructures of varying stiffness. |
