内容説明
The first book entirely dedicated to the topic emphasizes the relation between basic research and actual processing technologies. As such, it covers complex microstructures down to the nanometer scale, structure/property relationships and potential applications in key industries.
From the contents:
* Constitution
* Thermophysical Constants
* Phase Transformations and Microstructures
* Deformation Behaviour
* Strengthening Mechanisms
* Creep
* Fracture Behaviour
* Fatigue
* Oxidation Resistance and Related Issues
* Alloy Design
* Ingot Production and Component Casting
