Influence of component geometry and scan strategy on the residual stress in Selectively Laser Melted Nickel alloys


Unlike casting, Selective Laser Melting (SLM) powder bed system can be applied to build near-netshape components with complex geometries in a short lead time. Recently, SLM process has been applied for building production parts in aerospace and automotive industries. It fabricates components layer by layer by melting metallic powders directly. One concern with SLM of Ni superalloys is the presence of residual stresses, which are higher than the initial yield point of the material. Therefore there is huge interest for investigating the stress distribution of components of a high temperature Ni superalloy made by SLM. Measurements of the stress in a Nozzle Guide Vane will be performed and the results will be compared with a conventionally manufactured rod shaped component (experiment 1410579). Obtained result will be compared with computer modelling.
