MatéIS Laboratory

 

The Matériaux, Ingénierie et Science – MatéIS laboratory (Materials, Engineering and Science) is dedicated mainly to the study of structural and multifunctional materials, with a multidisciplinary approach including Physics, Chemistry and Mechanics.
MatéIS follows an holistic approach, which is applied during processing under multi-physic and complex conditions as well as the behavior in service. MATEIS' research focuses on relations between Process-Microstructure-Properties, with an experimental and/or a modelling approach.
MatéIS is involved on major societal issues: health, energy, environment, transport and building applications.
The laboratory, a joint research unit of INSA de Lyon, Université Claude Bernard – Lyon 1, and CNRS, comprising 180 researchers, has a long tradition of science implemented towards the industrial (clinical) scale and of collaborative projects. MatéIS focuses on bulk properties but is also strongly involved in the study of surfaces as described for each research team below.


 

 

 

 

Five teams are involved in the research activities of the Manutech-SLEIGHT Graduate-School.
 

The CorrIS team studies surface reactivity phenomena. By means of electrochemical characterization, CorrIS understands the reaction mechanisms that occur when a material is exposed to an aqueous environment.
In this context, CorrIS mainly studies the passivation phenomena that occur to protect materials. However, it is also concerned with the multi-functionality of materials by considering multiphysical coupling phenomena such as in stress corrosion or tribocorrosion.
Thus on the basis of a multi-scale approach, CorrIS contributes to the development of new biomaterials and also develops new grades of alloys dedicated to energy materials. To carry out its work CorrIS undertakes many experimental developments including local electrochemical measurements, measurement of tribocorrosion under irradiation and finally measurement of the dielectric characteristics of the passive film by surface plasmon measurements.

The CERA team works on the processing and the characterization of ceramics and ceramics-based composites. In addition to a complete sintering platform, several additive manufacturing of ceramics are available (robocasting, wire deposition, stereolithography), some located in the 3D Fab platform on LyonTech La Doua campus. Collaborative work with the Polymer, Glasses and Heterogenous Materials - PVMH and the METAL teams of MATEIS enable the process of polymer-ceramic and metal-ceramic composites. The team has also a strong expertise on the mechanical characterization of ceramics at macro and microscale.

I2B focuses on the development of new biomaterials and surfaces, and on the interactions between materials and biological environment, in situation very close to clinical cases. In collaboration with the CERA team, IB2 works on laser modification of surfaces to improve the mechanical adherence of living tissues on materials and biomaterials.

The METAL team works on the relationship between microstructures and thermo-mechanical properties of metallic materials. The activity of the METAL group covers several fundamental themes for metals in the field of materials science such as: production processes, heat treatments, the study of phase transformations and the understanding of mechanical properties through microstructure / property correlations, in situ tests and multi-scale simulations. These activities are linked to major societal issues in the fields of transport, energy and health.

The SNMS team is characterizing all types of materials and surfaces using electron and ion microscopies. They propose original methods of characterization involving SEM and TEM. Moreover, the SNMS team members are deeply involved in the CLYM platform, gathering heavy microscopy facilities in both St-Etienne and Lyon cities. The SNMS know-how is illustrated by their innovative studies on crystalline orientation mapping and sub-nanometric chemical analysis. They are also developing specific strategies to observe, in situ, at the meso- and nano-scales, the continuous modification of a stressed material. Latest developments are now devoted to the consideration of the environment on the material dynamics, in surface as well as volume, leading to operando approaches.
