A stress-affected chemical reaction front propagation is considered using the concept of a chemical affinity tensor. A reaction between an elastic solid constituent and a diffusing constituent, localized at the reaction front, is considered. As a res

Additive Manufacturing of Metal Alloys 2 : Microstructures, Post-processing and Use Properties

Autor: Patrice Peyre, Eric Charkaluk

Over the last decade or so, additive manufacturing has revolutionized design and manufacturing methods by allowing more freedom in design and functionalities unattainable with conventional processes. This has generated extraordinarily high interest i
