"This book is focused on the mechanical behavior of polycrystalline materials at decreasing grain size. The authors address the mechanical behavior and the defect structure of materials with grain sizes that range from meso- to micro-levels, and amorphous materials. The formation of dislocated structures and mechanical properties under reducing grain size is discussed and analysis is given for the stages of strain hardening and the effect of scaling. The book considers the internal stress fields that occur during the dislocation of plastic.Common behavior of these materials are described numerically via experimentally measured structural parameters."--Provided by publisher.
