In-situ strain monitoring during direct metal deposition of Inconel 718 by neutron diffraction
Throughout the AM process, complex thermal gradients, heterogeneous microstructure, and deep gradients of residual stresses (RS) within the bulk play a critical role for further mechanical solicitation of engineering (structural) components. Contrary to conventional techniques such as welding or casting, the strain evolution cannot be directly estimated by macroscopic measurements nor accurately predicted by computational modelling yet. Therefore, AM requires the implementation of new characterization approaches considering in-situ studies to disclose the controlling mechanisms and influence of fabrication parameters on phase and strain formation. Neutron diffraction at SALSA allows us to perform continuous monitoring in the bulk in shorter acquisition times thanks to the combination of high spatial resolution and flux2. This is a continuation from May2018 campaign and a resubmission from 2021 due to unavailable laser equipment at that time. In particular, we aim to investigate the effect of different energy inputs (from 0.025 ¿ 0.035 kJ/mm) with a similar setup and material at SALSA.
