“…Another way to combine in situ deformation experiments and the determination of crystallographic orientations is by the use of an automated electron backscatter diffraction system. Advantages and limitations of in situ electron backscatter diffraction experiments are well discussed by Wright and Nowell (2009).…”

Summary Two in situ plane‐strain deformation experiments on norcamphor and natural ice using synchronous recording of crystal c‐axis orientations have been performed with an automated fabric analyser and a newly developed sample press and deformation stage. Without interrupting the deformation experiment, c‐axis orientations are determined for each pixel in a 5 × 5 mm sample area at a spatial resolution of 5 μm/pixel. In the case of norcamphor, changes in microstructures and associated crystallographic information, at a strain rate of ∼2 × 10−5 s−1, were recorded for the first time during a complete in situ deformation‐cycle experiment that consisted of an annealing, deformation and post‐deformation annealing path. In the case of natural ice, slower external strain rates (∼1 × 10−6 s−1) enabled the investigation of small changes in the polycrystal aggregate's crystallography and microstructure for small amounts of strain. The technical setup and first results from the experiments are presented.

“…Apparently, with the increase of plastic strain in 316 steel, the BC value showed a downward trend, which is in agreement with the results in previous studies. 13,19 Beyond this point, other interesting phenomenon could be recognized from the quality of Kikuchi patterns. For one, we can see that the BC value preferentially decreased at the grain boundaries (see Figure 2(b)), the cause was probably due to the intergranular damage; for another, the change in BC value within each grain is also heterogeneous during the degradation process, which can be identified in Figure 2(c) to (e).…”

“…Generally, the kernel average misorientation is high in large deformed grains, whereby the high dislocation density and lattice rotation. 9,19 From the above results, we can know that the kernel average misorientation can be utilized to understand the local distortions, grain orientation change, and dislocation density level of metals, hence the KAM value can be used as an index for the assessment of the degradation degree in 316 ASS.…”

Type 316 steels have been heavily utilized as the structural material in many construction equipment and infrastructures. This paper reports the characterization of degradation in 316 austenitic stainless steel during the plastic deformation. The in-situ EBSD results revealed that, with the increase of plastic strain, the band contrast (BC) value progressively decreased in both grain and grain boundaries, and the target surface becomes uneven after the plastic tensile, which indicates that the increase of surface roughness. Meanwhile, the KAM and ρGND values are low in the origin specimen but increased significantly after the in-situ tensile. The results indicated that the KAM and ρGND are closely related to the deformation degree of the materials, which can be used as the indicator for assessing the degradation of 316 steel. Besides, the re-orientation of grain occurred after the tensile deformation, which can be recognized from the lattice orientation and local orientation maps.
