Nickel Base Single Crystals Across Length Scales

Professor Loeïz Nazé is an associate professor at the Mines ParisTech in the Materials Center. His areas of expertise include metallurgy and crystallography and his current areas of research include metallurgy, microstructures, and plastic deformation. Professor Naze studied engineering at the Lille University School of Engineering. Vincent Maurel, Ph.D. is a senior scientist with the Centre des Materiaux at the MINES Paris Tech. His areas of research include fatigue of materials at high temperature, mono and poly-crystalline superalloys, and analysis of coatings for turbine blades. Gunther Eggeler is Chair of the Materials Science and Engineering at Ruht-Universitate Bochum. Since 2012 he is director of the collaborative research centre SFB/Transregio 103 - From Atoms to Turbine Blades - Scientific Basis for a new Generation of Single Crystal Super Alloys. From 2000 to 2011 he served as director of the collaborative research centre SFB 459 - Formgedächtnistechnik (Shape Memory Technology). He is member of the scientific advisory boards of ICOMAT (International Conference on Martensitic Transformations) and ESOMAT (European Symposium on Martensitic Transformations). He is leader of a high temperature materials research group at the Max Planck Institut für Eisenforschung (MPIE) and full member of the North Rhine Westphalian Academy of Sciences. As material scientist Gunther Eggeler studies elementary microstructural processes which govern the deformation and transformation behaviour of structural and functional engineering materials Jonathan Cormier, Ph.D is He is an Associate Professor at ISAE-ENSMA. His current research focusses on Mechanical behavior of cast and forged Ni-based superalloys (isothermal and non-isothermal creep, fatigue, Thermo-mechanical fatigue); Damage processes and crack initiation in Ni-based alloys; Microstructure-Mechanical properties of superalloys; Constitutive modeling of the inelastic behavior of Ni-based alloys; Burner rig testing; durability of Thermal Barrier Coating systems. He currently serves as an editor of the Metallurgical and Materials Transactions A, B and E journals and was the recipient of the Jean-Rist Medal in 2015. Georges Cailletaud is a Professor at Mines ParisTech, a position he has held since 1994. He served as Director of the CNRS research unit at Centre des Matériaux (2006-2011) and deputy Director of the Department of Mechanics and Materials at Mines ParisTech (2008-2011). His main contributions deal with material modeling at various scales, specifically plastic and viscoplastic formulations for isothermal and non-isothermal loading, with crystal plasticity applied to single crystal and polycrystalline agregates, with damage development and crack initiation models. His work includes the developments of the model themselves and of the numerical methods needed for the numerical implementation in finite element codes. He is the author of two books.
