The following is an excerpt.

SFI CASA Professor Knut Marthinsen just visited the Center for Hierarchical Materials Design at Northwestern University in Chicago. He lectured on advanced characterization and modelling for aluminium process and alloy design.

Here is an abstract of his lecture:
NTNU (together with SINTEF) has a long tradition of experimental and theoretical research on light metals, in particular aluminium alloys, in close collaboration with other leading academic institutions and aluminium industries both inside Norway and abroad. Moreover, NTNU has state-of-the-art experimental facilities for nano-/ microstructure characterization, including advanced scanning electron microscopy (SEM) and transmission electron microscopy (TEM) laboratories, varies techniques for mechanical testing (incl. large scale crash testing) as well as facilities for high performance supercomputing.

Strong track record
In particular the TEM-group has a strong track record and international position within studies of precipitates in Al alloys, where various transmission electron microscopy methods have been combined with Atom Probe Tomography (APT) and ab initio quantum mechanical calculations (DFT), to reveal the atomic structure of a large number of precipitates in various Al-alloy systems. Another speciality has been the characterization and modelling of the microstrucure and texture evolution during thermomechanical processing of light metals, with particular focus on the development of physically based computer models for the simulation of deformation, recovery, and nucleation and growth reactions like precipitation, recrystallisation and grain growth.

Atomistic calculations
More recent activities has also to an increasing degree involved atomistic calculations and simulations (DFT), and the coupling and integration of various models into multi-scale and through process model approaches to simulate microstructures, properties and materials performance. The presentation gave an overview of competence and infrastructure and some glimpse of recent activities exemplifying the topics mentioned above, including precipitate studies, ab initio calculations of stacking fault energies and strength and formability of Al-alloys.
