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.

Experimental investigation of the nanoscale plasticity/damage mechanisms in phyllosilicates
Thomas Ferdinand van der Werf

The goal of my project is to gain insight into the elementary nanoscale plasticity/damage mechanisms of phyllosilicates using nanomechanical testing methods coupled to advanced transmission electron microscopy techniques. Phyllosilicates are important minerals as they can govern the frictional properties of faults in the lithosphere. However, the nanoscale deformation mechanisms of phyllosilicates are still not well understood. Hence, new insight in the nanoscale deformation mechanisms of phyllosilicates will help to better understand their frictional properties and their role in promoting creep at faults. Ultimately, this will aid in our knowledge of one of the most spectacular and hazardous geological manifestation: earthquakes.

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.

Contribution in to development of new medium steels of third generation of advance high strength steels for weightlighting automotive structure
Hamza Essoussi

Partout dans le monde il y a un intérêt croissant pour développer de nouveaux aciers : les aciers avancés à haute résistance (Advanced High Strength Steel « AHSS ») pour plusieurs applications, en particulier l’industrie automobile. En conséquence, la recherche est en cours dans les universités, instituts de recherche et les entreprises. Pourquoi donc ces matériaux sont sélectionnés pour les applications automobiles ? Plusieurs facteurs entraînent l’utilisation des AHSS pour les véhicules. Dans un premier lieu leur utilisation contribue à la réduction du poids du véhicule et du coup la réduction de la consommation du fuel et donc la réduction de l’émission du dioxyde du carbone CO2 émis dans l’atmosphère. Non seulement cela mais aussi leur grande résistance aux chocs et leur meilleure performance augmente la sécurité des passagers et tout cela avec un coût minimal de production. La troisième génération des aciers avancés (3rd generation of AHSS) a une structure composée, en particulier leur microstructure qui est généralement une microstructure multiphase dans le but d’avoir une combinaison parfaite entre résistance et ductilité pour qu’ils soient adaptés aux différents procédés de mise en forme (formage de tôle, soudage…) et les commercialiser. La troisième génération des AHSSs contient des quantités considérables des éléments contribuant à augmenter leur résistance, comme : la martensite, la bainite et ferrite. Le comportement composé de la structure multiphase et de l’effet TRIP (Transformation Induced Plasticity) ou l’effet TWIP (Twinning Induced Plasticity) lié à la présence de l’austénite résiduelle permet d’obtenir un excellent compromis entre résistance et ductilité qui est désiré pour les procédés de formage.

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.
