Metallurgy and Design of Alloys with Hierarchical Microstructures covers the fundamentals of processing-microstructure-property relationships and how multiple properties are balanced and optimized in materials with hierarchical microstructures widely used in critical applications. The discussion is based principally on metallic materials used in aircraft structures; however, because they have sufficiently diverse microstructures, the underlying principles can easily be extended to other materials systems. With the increasing microstructural complexity of structural materials, it is important for students, academic researchers and practicing engineers to possess the knowledge of how materials are optimized and how they will behave in service.
The book integrates aspects of computational materials science, physical metallurgy, alloy design, process design, and structure-properties relationships, in a manner not done before. It fills a knowledge gap in the interrelationships of multiple microstructural and deformation mechanisms by applying the concepts and tools of designing microstructures for achieving combinations of engineering properties―such as strength, corrosion resistance, durability and damage tolerance in multi-component materials―used for critical structural applications.
- Discusses the science behind the properties and performance of advanced metallic materials
- Provides for the efficient design of materials and processes to satisfy targeted performance in materials and structures
- Enables the selection and development of new alloys for specific applications based upon evaluation of their microstructure as illustrated in this work
