The book provides a framework for understanding materials processing during laser-based additive manufacturing by computational modeling and simulations. It thereby enables the users of this technique to improve the compositional, phase and microstructural evolution within the material and the subsequent mechanical, chemical, and functional properties of the manufactured components.
