This edition of "Production and Optimization of Nano Crystalline Materials" is a valuable asset for diploma, undergraduate, postgraduate students, industrialists, and product consultants. This book is aimed to provide all "necessary information about the basic types, properties, synthesis and engineering applications of nanocrystalline materials and also it provides a strong fundamental about plastic deformation, nano machining, mechanical alloying, process variables, experimental methodology and characterization of nanomaterials. The authors' objective of this edition is to provide comprehensive coverage of nano crystalline materials to increase the nano materials production and characterization activities of students to apply this advance technology to the real world applications.
