| Abstract Scope |
Tensile testing is the backbone of mechanical characterization. The possibility to combine mechanical testing with advanced imaging and characterization methods at high temperatures up-to 800°C opens new possibilities for materials research in the nuclear and space applications. In this work in-situ annealing experiments are shown, where the grain growth is observed via EBSD and EDS. Different annealing states are achieved for a variety of model alloy samples. Using EBSD information, high Schmid factor grains were identified and monitored during the in-situ tensile experiment enabling the image acquisition from the early onset of yielding in the first few grains. Furthermore, in-situ tensile tests on steel samples at a temperature of 800 °C clearly reveal slip band formation using BSD contrast. Results demonstrate the automated workflow of in-situ SEM imaging incorporating feature tracking to enable precise region of interest imaging. Additionally combining digital image correlation approach to map strains during deformation. |
