Nanostructural Metallic Materials-Nanoengineering and Nanomanufacturing

This chapter explores the development and application of nanostructural metallic materials, their processing and manufacture, and the need for control of structure postprocessing; the study of their mechanical properties and failure mechanisms, and the challenges for analytical techniques that can directly and quantitatively perform image solute distributions at near-atomic scale, and the principles underlying designing with nanometallics for reliability in service. Functional and structural nanometer-scale products based on natural nanomaterials science and technologiescan have great efficiencies in both performance and fabrication. Nanoengineering of materials structures, including the use of surface coatings and the development of novel nanocomposites, can provide better properties - in terms of strength-to-weight ratios, stiffness-to-weight ratios, fatigue lives, wear resistance, and corrosion resistance, without the use of rare earth alloying metals, and thus improving the energy efficiency in materials processing and fabrication.
