High temperature in‐situ experiments not only require a conventional equipment, but also special devices such as a double tilting straining holder, a double tilting heating holder (1500 K), a high vacuum specimen chamber (a few 10 −6 P ≅ 10 −8 Torr) and a low light level, high resolution, visualization and recording system. Some preliminary conclusions, regarding the representativeness of the in‐situ experiments in HVEM, may be derived from the recrystallization and deformation tests performed at ONERA. The fact that the results of these experiments are in good agreement with those obtained through macroscopic tests, a posteriori demonstrates that the former experiments are representative of the bulk material.
