Philippe BuffatBorn in Lausanne (Switzerland) in 1942. EPUL physics engineer diploma in 1967 and EPFL PhD in physics in 1976. From 1966 he studies at the Experimental Physics Laboratory (Prof. J.P. Borel) the physical properties peculiar to the very small size metal crystals and gets a PhD degree for his thesis "Abaissement de la température de fusion de petits cristaux d'or par effet de taille thermodynamique" (Lowering of the melting temperature of small gold crystals by thermodynamic size effect). In 1971, he starts to develop an electron microscopy facility available to all EPFL students and researchers (nowadays Centre Interdisciplinaire de Microscopie Electronique CIME) that he manages till 2007. In parallel he teaches the principles of electron microscopy and the Experimental methods of physics at the Physics/Basic Sciences School (SB). In addition, he trains a large part of the facility users. Honorary professor BS/EPFL he carries-out a free-lance research at CIME and in collaboration with the Institute of Crystallography of the Russian Academy of Sciences (ICRAS, Moscow) and the International Centre of Electron Microscopy for Material Science (IC-EM AGH Krakow) This activity covers all the techniques related to transmission and scanning electron microscopy applied to materials science and solid-state physics. His interest is directed towards the structure of nanocrystals, their size effects and behavior under strong electron irradiation, the phase transitions in perovskites, the characterization of nanophases, multilayer and interface structures of crystalline materials and bioceramics. More recently a large research part has moved to understanding/pointing-out the adequacy between the limits of the instruments and their interpretation means in regard of their use in a multiusers facility with a large turnover and a wide range of materials/structures. He is past-president (2006-2007) of the Société Française des Microscopies (Sfµ), honorary member of the Sfµ and of the Swiss Society of Optics and Microscopy (SSOM).
Cyril CayronMes recherches: J'ai travaillé comme microscopiste/cristallographe/métallurgiste sur des projets très variés comme les aciers pour le nucléaire, les alliages titane et nickel pour l'aéronautique, les interconnections en cuivre pour la microélectronique, les piles à combustible haute et basse température, le silicium photovoltaïque hétérojonction et monolike, les batteries au lithium à base de LiFePO4 et silicium. Derrière la plupart de ces sujets de recherche appliquée se cachent des problèmes de recherche fondamentale comme celui lié aux transformations de phases. J'ai donc été amené à travailler sur ce sujet passionnant et j'ai pu démontrer que les variants cristallographiques générés par des transitions structurales forment une structure algébrique de groupoïde. Ces travaux ont mené au développement du logiciel de reconstruction des grains parents à partir de données EBSD appelé ARPGE et distribué dans plus de 20 pays. En 2013-2015 j'ai proposé un nouveau modèle cristallographique pour les transformations martensitiques fcc-bcc dans les aciers, comme une alternative à la théorie phénoménologique de la transformation martensitique. Ce modèle a été depuis étendu aux transformations fcc-hcp (type cobalt), bcc-hcp (type titane) et bcc-fcc (type laiton), ainsi qu’à differents modes de maclage mécanique dans les métaux fcc et hcp. Ce modèle à sphères dures montre que la transformation implique une «distorsion angulaire», forme plus générale que le cisaillement. Le modèle prévoit la possibilité que le plan d’interface de certaines macles mécaniques ne soit pas un plan invariant. Un tel cas de maclage « exotique » a été observé expérimentalement par EBSD en 2017 dans un monocristal de magnésium pur. Je travaille maintenant à définir de manière algébrique les concepts de variants (orientation, distortion, correspondance), et sur les types de macles mécaniques (I, II, et d'autres oubliés des théoriques classiques). Mon parcours : 2014-maintenant: Collaborateur scientifique à l'EPFL/LMTM, Neuchâtel, Suisse. J'aide le professeur Roland Logé dans ses travaux de recherche sur les liens entre les fortes déformations, les textures, les tailles de grains et les transformations de phases (diffusives et displacives). Je suis en charge de la salle de métallographie et des caractérisations SEM, EDS, EBSD, TEM, HRTEM. Je codirige trois thèses (Annick Baur, Margaux Larcher, Céline Guidoux). Je suis reviewer pour Acta Mater., Scripta Mater., Acta Cryst., J. Appl. Cryst., Mater. Charact., etc. 2000-2014: Ingénieur de recherche et responsable du groupe Nanocaractérisation, CEA/LITEN, Grenoble, France. 2012 : Habilitation à Diriger des Recherches (HDR). 1996-2000: Thèse sur l'étude par microscopie électronique de composites à matrice aluminium. Directeur de thèse Philippe Buffat, CIME, EPFL, Lausanne, Suisse. J'ai pu montrer un lien cristallographique entre différentes phases des alliages 2xxx et 6xxx et proposer pour la première fois une structure complète pour la phase beta prime des nanoprécipités. 1995-1996: Scientifique du contingent, travail sur les écrans électrochromes, COGIDEV, Rueil-Malmaison, France, fondé par M. André Giraud, ancien ministre de la défense et ancien ministre de l’industrie. 1992-1995: Ecole Nationale Supérieure des Mines de Nancy, France
