In-situ study on the load partitioning in directionally solidified NiAl-(Cr,Mo) eutectics

Abstract: NiAl-Cr-Mo eutectic composites show promising characteristics regarding their usage for high-temperature structural applications. The composites consist of the intermetallic NiAl-phase as well as a Cr(Mo)-solid solution, whereas the latter forms a fibrous or lamellar microstructure within the NiAl through directional solidification. Mechanical and thermal loading results in phase-specific strain that affects the overall mechanical behaviour. The analysis of the load partitioning between the phases and the composite’s elastic anisotropy enables the validation and optimization of simulation models. For this purpose, small cuboid samples will be subjected to define compressive loading with increasing load steps. ToF in situ neutron diffraction at ENGINE-X constitutes an important tool to acquire data from all contributing phases in load direction and transverse e to it at the same time.
