IUTAM Symposium on Mechanical Behavior and Micro-Mechanics of Nanostructured Materials

AbstractSurface and interface stresses, which are intrinsic thermodynamic quantities associated with all types of solid surfaces and interfaces are reviewed. A simple model for one type of interface stress is presented. These stresses can strongly influence the structure and mechanical behavior of nanostructured materials such as multilayered materials withultrathin layer thicknesses.

Structural Scale

Nanocrystalline materials have been attracting rapidly increasing interest in the last decade and have the potential of revolutionizing traditional materials design in many applications via atomic-level structural control to tailor the engineering properties. In addition to interesting physical properties in the areas of magnetics, catalysis, and optics, this class of materials exhibits a broad range of fascinating mechanical behavior. Superplastic deformation behavior has been observed at significantly lower temperatures in ceramic nanoscale powders. Ultrahigh hardnesses have been measured in nanoscale superlattices made of metallic and ceramic materials. Tensile and compressive strengths in nearly all material systems studied have shown anomalously high values at the nanometer-length scale.The development of nanostructured materials is now raising the question of how the different properties change as the microstructural scale is reduced to nanometer dimensions. Among potential applications of nanostructured materials, the design to achieve optimum mechanical properties is a common concern. Traditionally the mechanical strength σ of crystalline materials is believed to be largely controlled by the grain size d, often in the manner described by the Hall-Petch relationship σ= kd−1/2 +σ0. As the structural scale reduces to the nanometer range, the limits to the conventional descriptions of yielding need to be established, and new mechanisms that may come into play at these very small dimensions need to be explored and studied. In addition the intrinsically high interface-to-volume ratio of the nanostructured materials may enhance interface-driven processes to extend the strain to failure and plasticity. These potential gains will have profound technological impact in a wide range of engineering applications, and need to be validated and exploited.

Further Development

Ceramics, such as Al2O3 and SiC have numerous current and potential uses in applications where high temperature strength, hardness, and wear resistance are required often in corrosive environments. These materials are, however, highly anisotropic and brittle, so that their mechanical behavior is often unpredictable. The further development of these materials will require a better understanding of the basic mechanisms controlling deformation, wear, and fracture.The purpose of this talk is to describe applications of TEM to the study of the deformation, wear, and fracture of Al2O3. Similar studies are currently being conducted on SiC and the techniques involved should be applicable to a wide range of hard, brittle materials.
