A new high-temperature detector is used in combination with heating stages for collecting backscattered electrons, evaluating material transformations at high temperatures. It offers good opportunities for high-temperature experiments in various atmospheres, potentially adaptable to any type of SEM.
A new high-temperature detector dedicated to the collection of backscattered electrons is used in combination with heating stages up to 1050 degrees C, in high-vacuum and low-vacuum modes in order to evaluate its possibilities through signal-to-noise ration measurements and different applications. Four examples of material transformations occurring at high temperature are herein reported: grain growth during annealing of a rolled platinum foil, recrystallisation of a multiphased alloy, oxidation of a Ni-based alloy and complex phase transformations occurring during the annealing of an Al-Si coated boron steel. The detector could be potentially adapted to any type of SEM and it offers good opportunities to perform high-temperature experiments in various atmospheres.
