Metal Microstructures in 3D and 4D

June 17, 2021 @ 15:00 16:00 CEST

Speaker: prof. dr. Dorte Juul Jensen, from Danish Technical University, Risoe, Denmark.

Metal Microstructures in 3D and 4D.

Characterization of metal microstructures in 3D is not new. But a new ‘wave’ of experimental methodologies emerged during the late 1990ies – early 2000ies, fueled by novel possibilities at large international synchrotron facilities. Thereby also 4D (x,y,z,time) investigations became possible. A short ‘evolution history’ of these methods is presented, with focus on today’s possibilities and limitations. Examples of applications for recent studies of recrystallization are given, highlighting scientific questions which cannot be addresses by more traditional experimental techniques. Possibilities for direct linking the experimental data to simulation tools are also discussed. Finally a view towards future development of similar 3D/4D techniques operating in home laboratories is given and it is demonstrated how grain mapping by these methods may be improved using artificial intelligence (deep learning) methods.

The session was chaired by prof. Leo Kestens (Ghent University).
