Al3Sc-Dislocation Interactions at 400oC
The following videos show dislocation-Al3Sc interactions observed during a heating experiment performed in situ in the TEM. Thermal stresses arising during heating are the source of the dislocation motion. The sample is an Al-4Mg-0.3Sc alloy with a bimodal distribution of Al3Sc consisting of coherent 20 nm particles and semi-coherent 150 nm particles. The interactions shown in these videos are with the latter.
