My research has been selected and featured in an article by the CNRS-Ingénierie (INSIS) entitled "De nouveaux matériaux métalliques combinent résistance mécanique et ductilité" ("Novel metallic materials which combine large strength and ductility").
The text and the interview (only in French) can be found in:
Top: (left) Transmission electron microscopy image of an amorphous ZrCu nanolaminate, showing the arrest of a shear band at the interface between two layers. (right) Micropillar compression curve, revealing large plasticity.
Bottom: (left) Scanning/transmission electron microscopy image of a crystalline/amorphous nanogranular micropillar fabricated by PLD, showing the formation of surface shear bands. (right) Micropillar compression curves illustrating the high yield strength (> 3 GPa) and ductility of this material (> 10%).
