The overall objective of the research activity of Prof. Hosni Idrissi is a fundamental investigation of the physics of defects dynamics in inorganic materials dominated by internal or external interfaces such as nanocrystalline metallic and metallic glass thin films, hybrid multilayers combining crystalline and amorphous systems as well as bulk coarse-grained metals and alloys involving twinning-induced-plasticity (TWIP) and transformation-induced-plasticity (TRIP). The core questions concern the competition or the synergy between the nanoscale elementary mechanisms, which ultimately control the strength and ductility of these materials. The overall research approach is based on the design and use of quantified new nanocharacterization tools including nanomechanical testing methods (lab-on-chip, nanoindentation, etc.) coupled with advanced transmission electron microscopy (TEM) techniques (aberration corrected high resolution TEM imaging and spectroscopy, electron tomography, orientation and nanostrain mapping in TEM, in-situ TEM nanomechanical testing, etc.) to unravel the mechanisms under interest.

Interface Controlled Super Tough metal/metallic glass Hybrid Nanolaminate Coatings
Hui Wang

In our research, we characterize the mechanical properties and nanoscale plasticity mechanisms in a tri-layer model system of Al/Al2O3/Al film deposited on Si substrate at room temperature through DC magnetron sputtering. The mechanical response of the films was investigated using nanoindentation as well as a UCLouvain lab-on-chip tensile method based on the relaxation of internal stresses in an actuator beam to pull on the specimen after chemical etching of the underlying sacrificial layers. The results of nanoindentation confirmed the occurrence of creep. Furthermore, by reducing the thicknesses of the alumina layer, a small decrease of the Young’s modulus and hardness was observed. The tri-layer structure becomes more sensitive to different strain rate, which was manifested by nanoindentation test. Also the in-situ TEM nanotensile tests showed an unexpected high ductility can be attained and the high ductility of the tyilayer Al/Al2O3 /Al system is maimly related to the deformation induced crystallization in Al2O3 layer and grain boundary sliding in Al layer.

Though hybrid nanolaminates
Paul Baral

I am particularly interested in the mechanical characterization of the multi layered materials and their deformation mechanisms. I use nanoindentation and lab-on-chip techniques together with TEM observations of the deformed nanolaminates to enhance the understanding of their surprising mechanical behavior.
