Abstract

The production of metallic parts via laser-powder bed fusion (L-PBF) additive manufacturing is rapidly growing. To use components produced via L-PBF in safety-critical applications, a high degree of quality confidence is required. This qualification can be supported by means of a validated thermomechanical model capable of predicting the final residual stress state and subsequent lifetime. In this work, we use high-energy X-ray diffraction to determine a three- dimensional residual strain and stress state of a Ti-6Al-4V L-PBF component. The experimental results are used to aid in validation of simulations. Strong agreement is observed between the experiments and the model predictions.
