Abstract
Additive manufacturing is a transformative approach to industrial production that enables the creation of lighter, stronger parts and systems, while bringing digital flexibility and efficiency to manufacturing operations [1]. Despite the constant progress in the field, there are still a lot of challenges that must be addressed. In the case of metal components, residual stress caused by the unique thermal cycle in AM is the critical issue since the steep stress gradients can generate distortion and increased fragility, which can lead to serious deterioration of the end-use parts [2]. The present study tries to prove that neutron diffraction is one of the most versatile and powerful analysis tools for internal stress, as it allows the determination of the complete 3D stress tensor on real sized components, even in-situ or in-operando conditions. The stress field in an aluminum additive manufactured support is mapped out under load, by determining 3 orthogonal components.
