Defect Structure and Properties of Nanomaterials, 2nd Edition

Book Description

Defect Structure and Properties of Nanomaterials: Second and Extended Edition covers a wide range of nanomaterials including metals, alloys, ceramics, diamond, carbon nanotubes, and their composites. This new edition is fully revised and updated, covering important advances that have taken place in recent years.

Nanostructured materials exhibit unique mechanical and physical properties compared with their coarse-grained counterparts, therefore these materials are currently a major focus in materials science. The production methods of nanomaterials affect the lattice defect structure (vacancies, dislocations, disclinations, stacking faults, twins, and grain boundaries) that has a major influence on their mechanical and physical properties.

In this book, the production routes of nanomaterials are described in detail, and the relationships between the processing conditions and the resultant defect structure, as well as the defect-related properties (e.g. mechanical behavior, electrical resistance, diffusion, corrosion resistance, thermal stability, hydrogen storage capability, etc.) are reviewed.

In particular, new processing methods of nanomaterials are described in the chapter dealing with the manufacturing procedures of nanostructured materials. New chapters on (i) the experimental methods for the study of lattice defects, (ii) the defect structure in nanodisperse particles, and (iii) the influence of lattice defects on electrical, corrosion, and diffusion properties are included, to further enhance what has become a leading reference for engineering, physics, and materials science audiences.

  • Provides a detailed overview of processing methods, defect structure, and defect-related mechanical and physical properties of nanomaterials
  • Covers a wide range of nanomaterials including metals, alloys, ceramics, diamond, carbon nanotubes, and their composites
  • Includes new chapters covering recent advances in both processing techniques and methods for the study of lattice defects
  • Provides valuable information that will help materials scientists and engineers highlight lattice defects and the related mechanical and physical properties
