Fast in-situ annealing stage coupled with EBSD: A suitable tool to observe quick recrystallization mechanisms

Abstract : A heating stage has been developed to perform in-situ annealing in a SEM equipped with an EBSD system in order to study recrystallization mechanisms. High temperature treatments could then be performed inside the SEM, up to 1180 °C and with high heating and cooling rates (~ 100 °C s− 1). Samples were cooled down to room temperature to perform EBSD orientation mapping in between successive short-duration heat treatments. Microstructure evolution snapshots obtained this way allow gaining an insight into recrystallization mechanisms. The interest of such experiments is shown for two examples: static recrystallization of cold deformed pure tantalum and post‐dynamic evolution of hot-deformed Zircaloy4.
