The effect of additive manufacturing growth direction on the thermomechanical deformation behaviour of IN718 components

Abstract: Despite the tremendous promise of selective laser melting (SLM) additive manufacturing technique, it is particularly challenging to apply it to the hard-to-weld, high temperature alloys. Consequently, profound understanding must be sought of the relationship between the deposition conditions and texture, microstructure etc., seeking to avoid defect formation and ensure optimal stiffness, strength and creep resistance under the loading expected in service, e.g. in aeroengine turbine. Neutrons will allow performing a comparative study of the deformation behaviour of differently grown SLM samples of Ni superalloy at room and elevated temperatures. Using the insight obtained into inter- and intra-granular strain and stresses, advanced numerical models will be validated and used to pave the way to future improved designs of materials and processes.
