This PhD thesis focuses on the study of the relationship between (La,Sr)MnO3 (LSM) thin film’s microstructure and their functional properties in memristive devices. Valence Change Memories (VCMs), which rely on resistive switching phenomena, are exciting candidates for the next generation of non-volatile memories as they offer fast writing speed, h...
Les performances de détection de défauts des contrôles non destructifs par ultrasons sur les matériaux polycristallins, peuvent être altérées par une forte atténuation du faisceau ultrasonore induite par la diffusion des ondes ultrasonores par les joints de grains. L’objectif de ce travail de thèse est d’identifier les caractéristiques microstructu...
The macroscopic properties of metals and metal alloys are highly dependent on their microstructure. Numerical modeling is a very powerful instrument for understanding its evolution under given thermomechanical conditions. The need to understand the processes at the microscopic scale that drive phenomena such as crystal plasticity, recrystallization...
WC-Co cemented carbide is a two phase system constituted of a cobalt based binder matrix embedding hard tungsten carbide grains. This material is especially used in fields such as metal cutting or mining, where high mechanical properties are required. Therefore, the microstructure is a key parameter to control to optimize the mechanical properties ...
