Abstract Scope |
The mechanical performance of Metal Additive Manufacturing (MAM) components is potentially affected by complex gradients of residual stresses in 3D. These initial state would evolve in jet unknown trends under in-operando conditions. Therefore, AM structural components require exhaustive characterization approaches towards their safe application.
Neutron strain diffraction enhances mapping of the full strain tensor within the bulk of polycrystalline materials. This non-destructive technique allows the investigation of complete development cycles on a same sample and also in-situ/operando investigations.
Research at SALSA (Stress Analyser for Large Scale engineering Applications) at the European neutron source ILL (Grenoble,FR) will be presented encompassing critical aspects in residual stress analysis: strain monitoring during direct energy deposition, the non- symmetrical nature stress fields with respect to the geometry and the mechanical properties at high temperature. |
