🔬 In this work, we present a novel synthesis strategy to fabricate nanostructured thin film metallic glasses (TFMGs) with tailored local heterogeneities by exploiting the potential of Pulsed Laser Deposition (PLD), managing to extend MG’s mechanical size effect range up to the micrometer scale. Specifically we show that, PLD-deposited TFMGs exhibit high yield strength (σy >2.8 GPa) and up to 6.7 % elastoplastic deformation which are maintained for large micropillar dimension of 1.3 × 3 µm (diameter x height). Such values significantly surpass those of traditional families of bulk and TFMGs, where size effects on σy and plasticity are activated for intrinsic dimensions < 0.5 µm.

20 May 2025: Invited Seminar at The University of Arizona
I was very pleased to visit the University of Arizona Materials Science and Engineering department in Tucson, where I had the opportunity to deliver a seminar invited by Prof. Horst Hahn. My talk focused on my research activities at LSPM-CNRS involving the synthesis of nanostructured metallic thin films with enhanced and tunable mechanical properties (see below).
Moreover, I sincerely thank Prof. Hahn and the entire MSE department the kind welcome and engaging scientific discussions. I look forward to future collaborations!
