Le fluage est la tendance des matériaux solides à subir une déformation progressive permanente sous l'influence des contraintes. Il se produit à la suite d'une exposition à long terme du matériau à des niveaux de contrainte inférieurs à sa limite d'élasticité. Le fluage est plus sévère dans les matériaux exposés à des températures élevées (c'est-à-dire près du point de fusion) pendant longtemps. Les matériaux à gradation fonctionnelle (FGMs) sont une nouvelle génération de matériaux d'ingénierie, dans lesquels les composants ou leur contenu varient en fonction des coordonnées de position, ce qui leur permet d'offrir des performances uniques. Le concept de FGM a été proposé en vue d'obtenir une nouvelle classe de matériaux composites, composée de céramique résistante à la chaleur du côté haute température et de métaux durs avec une conductivité thermique élevée du côté basse température, avec une variation progressive de la composition de la phase céramique à la phase métallique. L'application du concept de MGF aux MMC a conduit au développement de matériaux/composants, conçus dans le but d'utiliser un renforcement sélectif dans les régions où des propriétés améliorées telles que l'augmentation du module, de la résistance et de la résistance à l'usure sont nécessaires.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Creep is the tendency of solid materials to undergo permanent gradual deformation under the influence of stresses. It occurs as a result of long term exposure of material to stress levels that are below its yield strength. Creep is more severe in materials that are exposed to elevated temperature (i.e. near melting point) for long time. Functionally graded materials (FGMs) are a new generation of engineering materials, in which the constituents or their contents vary with respect to position coordinates, which enable them to offer unique performance. The concept of FGM has been proposed with a view to obtain a new class of composite materials, consisting of heat resistant ceramic on the high temperature side and tough metals with high thermal conductivity on the low-temperature side, with a gradual variation in composition from the ceramic to metal phase. The application of concept of FGMs to MMCs has led to the development of materials/components, designed with the purpose of using selective reinforcement in regions where enhanced properties like increased modulus, strength and wear resistance are required. 108 pp. Englisch.
