The development of fast acquisition EBSD systems, coupled with heating stages which can fit inside the SEM, has advanced the interest in in-situ experimentation. Phenomena, such as phase transformations and recrystallisation, may now be observed directly in real-time and with high spatial resolution. These processes can then be linked to the underlying microstructure, yielding a detailed insight into how materials behave in different environments.
In this presentation the requirements and configuration for in-situ EBSD experiments will be discussed:
The results from in-situ EBSD heating experiments will be presented.
This will include a study of the transformation of austenite to ferrite in plain carbon steel and the recrystallisation in a bronze alloy strip cast on a steel substrate.
The microstructural changes observed during these experiments will be shown using EBSD maps, grains size and illustrating the crystallographic texture that evolves during:
a heating cycle from ferrite to austenite and cooling to ferrite
the recrystallisation microstructure for bronze and steel during isochronal heating.
What attendees will gain:
An overview of this growing application for materials characterisation
An understanding of the benefits of in-situ EBSD analysis
An in-depth appreciation of the in-situ EBSD challenges
The ability to ask experts in this field questions during the talk
