Annealing experiments on metal alloys

In collaboration with


Why to perform in situ deformation/annealing experiments on alloys?

Deformation experiments at the LMGC, Montpellier (France)

Annealing experiments at the Géosciences Montpellier (France)

  • Annealing experiments in an external oven/oil bath
  • Microstructural analysis in the Crystal Probe SEM-EBSD facility (Fig. 2)

Challenges and drawbacks


Fig. 3 - Textural change of the zinc alloy during annealing experiments. Color coding in the EBSD maps (left) corresponds to grain orientation that is shown in pole figures (top) in details. Maps are identical scale, but not the same area is shown. Note the overall grain growth that results in less variable orientation as annealing progresses.

Preliminary implications
