Scope Large scale facilities, such as synchrotron and neutron beamlines, play a growing role in the investigation of phase transformation mechanisms, microstructural evolution, and the mechanical properties of steels, thanks to their resolution compared to laboratory devices, and their versatility for time-resolved investigations. This symposium aims to facilitate exchanges about present-day practices in the usage of these instruments and future opportunities in this field to understand the physical metallurgy of Fe-based alloys.

The scope of this symposium comprises studies on steels (carbon steels, stainless steels, maraging steels and special products) using large scale facilities dedicated to the study of:

- In-situ characterization of solid-state phase transformation and microstructure evolution during processing and simulated manufacturing (recovery, recrystallization, nucleation and growth, precipitation, partitioning, aging, etc.)

- The link between microstructure and properties at phase scale (local strain/stress determination, residual stresses, deformation-induced transformations, damage, etc.)

- In-operando characterization of parts (residual stresses, fracture, damage, toughness, fatigue, etc.)

Contributions using the following techniques are expected: HEXRD, HEDM, MicroLaue Diffraction, SAXS/SANS, Anomalous scattering/diffraction, Holo-tomography, Laminography, Tomography, Neutron Diffraction, etc.
