This work clarifies the actual conditions under which dynamic transformation occurs in steel during hot deformation. Using synchrotron X-ray diffraction, it demonstrates that conventional methods often overestimate both the extent and the temperature range of such transformations.

This paper highlights the extreme sensitivity of the itinerant magnetism of the Fe-sublattice to the presence of Mo in the crystal lattice of HfFe2. It sheds light on the strong coupling between lattice and spin degrees of freedom in Hf1-xMoxFe2 intermetallic compounds.

The kinetics complex and mechanisms of the hot corrosion of a superalloy for aeronautical applications were determined through accurate characterizations at the nanometric scale.

We have grown epitaxial GdVO3 thin films onto different substrates, and revealed that epitaxial strain engineering has a significant influence on the type of spin ordering and allowed tuning the antiferromagnetic transition temperature. This opens new routes for oxide based electronic devices.

This work evidences that the electrical properties of high entropy alloys can be tuned by the addition of a sixth elements. Depending on the nature and the concentration of this element, the temperature coefficient of resistance can be either positive, negative or close to zero.

Because science is built on curiosity, commitment... and above all the desire and pleasure of working together.

Congratulations to Stéphane Mangin on his election to the European Academy of Sciences!
The European Academy of Sciences (EURASC) is an independent, non-governmental, not-for-profit European organisation of researchers and engineers.
Its aim is to promote fundamental research and excellence in science and technology.

The second edition of the Journées « Nano-Est » will take place on October 1st and 2nd, 2025, at École des Mines Nancy / Institut Jean Lamour in Nancy.
