Märksõnad:
Superplasticity and Grain Boundaries in Ultrafine-Grained Materials, Second Edition, provides cutting-edge modeling solutions surrounding the role of grain boundaries in processes such as grain boundary diffusion, relaxation and grain growth. In addition, the book's authors explore the formation and evolution of the microstructure, texture and ensembles of grain boundaries in materials produced by severe plastic deformation. This updated edition, written by leading experts in the field, has been revised to include new chapters on the basics of nanostructure processing, the influence of deformation mechanisms on grain refinement, processing techniques for ultrafine-grained and nanostructured materials, and much more.
  • Provides practical applications and methods for the proper implementation of models, allowing for more effective complex metal forming processes
  • Features new chapters on the microstructure, mechanical behavior and functional properties of HCP metals, processing ultrafine-grained and nanostructured materials, and more
  • Covers experimental assessment and computational modeling techniques for adiabatic heating and saturation of grain refinement during SPD of metals and alloys
