Sample Storage for EBSD

As sample preparation is so critical, it make sense to store your samples so that you do not need to repolish them. A suitable place to store samples is in a desiccator, or at the very least in a clean room in appropriate containers or drawers.

However, the trained PINN model can be reused multiple times, with a testing and reprocessing time of approximately 10 min for a single EBSD distribution. This is advantageous for the processing of batch EBSD distributions and for the calculation of large-scale finite element models.

Experimental measurement of dislocation density in metallic

After 5% deformation, a higher dislocation density is expected in austenite compared to that in ferrite. The XRD and HR-EBSD results are similar to each other, and both indicate a dislocation density that is twice as high in austenite as in ferrite for this state (approximately 1.7 × 10 14 m −2 and 0.7 × 10 14 m −2, respectively
