Introduction to Heterostructured Materials provides updates on the historical perspective of the development of these materials, which is followed by a review of the basic background on mechanical behaviors and properties of metals and alloys. Next, both the definition and the fundamental principles and deformation behavior of heterostructured materials are covered, as well as their processing and properties and various design principles. The book supports graduate students and researchers entering this field, senior scientists who are already working in this field, engineers in the manufacturing industry, and professors who are teaching advanced materials and technologies. Heterostructured materials not only possess superior mechanical and/or physical properties that are not accessible to their conventional homogeneous counterparts, but they are also conducive to large-scale industrial production at low cost.
