Available in PDF, EPUB and Kindle. Book excerpt: L'alliage L-605 est un superalliage base cobalt combinant une haute résistance et une bonne ductilité, de plus il est biocompatible et présente une bonne résistance a la corrosion. Dû a son inertie chimique dans le corps humain, ce matériau a été utilise avec succès pour fabriquer des valves cardiaques et des stents. Le contrôle de la microstructure peut influencer grandement les propriétés mécaniques : notamment un raffinement des grains est susceptible d'augmenter d'avantage la résistance et serait intéressant pour permettre de fabriquer des stents selon une architecture plus fine. L'ajustement de la distribution de taille de grains à travers le phénomène de recristallisation lors de la déformation à chaud apparait comme une solution pratique pour ajuster les propriétés mécaniques du matériau. Pour contrôler la microstructure et choisir les conditions de procédé optimales, les mécanismes mis en jeu lors de la recristallisation dynamique et l'effet des conditions de déformation sur la taille de grain doivent être compris et prévisibles par des outils théorique. Les propriétés mécaniques du matériau à haute température sont déterminées par des essais de compression à chaud. L'évolution microstructurale du matériau lors de la compression est analysée par microscopie optique et électronique (EBSD, TEM). Le phénomène de recristallisation dynamique continue est mis en évidence, et procède par nucléation de nouveaux grains aux joints de grain. La corrélation entre le comportement mécanique à chaud et l'évolution microstructurale est déterminée expérimentalement. Les conditions optimales de déformation impliquant la recristallisation dynamique sont déterminées, et la microstructure résultante est étudiée en détail. De nouveaux outils théoriques permettant de prévoir les conditions de recristallisation et d'extraire les paramètres physiques du matériau a partir des données expérimentales sont proposés. Enfin, la recristallisation dynamique est modélisée analytiquement, et permet de prédire le comportement mécanique et l'évolution de la taille de grain lors de la déformation.

Available in PDF, EPUB and Kindle. Book excerpt: This cutting-edge book focuses on the emerging area of biomaterials and biodevices that incorporate therapeutic agents, molecular targeting, and diagnostic imaging capabilities The design and development of biomaterials play a significant role in the diagnosis, treatment, and prevention of diseases. When used with highly selective and sensitive biomaterials, cutting-edge biodevices can allow the rapid and accurate diagnosis of disease, creating a platform for research and development, especially in the field of treatment for prognosis and detection of diseases in the early stage. This book emphasizes the emerging area of biomaterials and biodevices that incorporate therapeutic agents, molecular targeting, and diagnostic imaging capabilities. The 15 comprehensive chapters written by leading experts cover such topics as: The use of severe plastic deformation technique to enhance the properties of nanostructured metals Descriptions of the different polymers for use in controlled drug release Chitin and chitosan as renewable healthcare biopolymers for biomedical applications Innovated devices such as “label-free biochips” and polymer MEMS Molecular imprinting and nanotechnology Prussian Blue biosensing applications The evaluation of different types of biosensors in terms of their cost effectiveness, selectivity, and sensitivity Stimuli-responsive polypeptide nanocarriers for malignancy therapeutics

Book excerpt: Provides a thorough explanation of the basic properties of materials; of how these can be controlled by processing; of how materials are formed, joined and finished; and of the chain of reasoning that leads to a successful choice of material for a particular application. The materials covered are grouped into four classes: metals, ceramics, polymers and composites. Each class is studied in turn, identifying the families of materials in the class, the microstructural features, the processes or treatments used to obtain a particular structure and their design applications. The text is supplemented by practical case studies and example problems with answers, and a valuable programmed learning course on phase diagrams.
