Casting Aluminum Alloys, Second Edition, the follow up to the fall 2007 work on the structure, properties, thermal resistance, corrosion and fatigue of aluminum alloys in industrial manufacturing, discusses findings from the past decade, including sections on new casting alloys, novel casting technologies, and new methods of alloys design. The book also includes other hot topics, such as the implementation of computational technologies for the calculation of phase equilibria and thermodynamic properties of alloys, the development of software for calculation of diffusion processes in aluminum alloys, computational modeling of solidification microstructure and texture evolution of multi-component aluminum materials.In addition to changes in computational predictive abilities, there is a review of novel casting aluminum alloy compositions and properties, as well as descriptions of new casting technologies and updates to coverage on the mechanical properties of aluminum casting alloys.- Presents a discussion of thermodynamic calculations used for assessing non-equilibrium solidifications of casting aluminum alloys- Expands coverage of mathematical models for alloy mechanical properties, helping facilitate the selection of the best prospective candidate for new alloy development- Contains a new section that describes the self-consistent evaluation of phase equilibria and thermodynamic properties of aluminum alloys

Phase Diagrams for Binary and Multicomponent Aluminum Systems

Abstract

The first chapter deals with the most fundamental issues pertaining to the whole area of casting aluminum alloy design and manufacture. Of course, we talk about phase diagrams. In the second edition of this book a rigorous thermodynamics-based approach was adopted to deal with phase diagrams. It is called “self-consistent evaluation of phase equilibria and thermodynamic properties of materials” or, using a different term, “critical assessments of thermodynamic and phase equilibria information.”

This is done to ensure consistency and the application of the same rigorous mathematical approach to all aluminum bearing alloys. In this book, it was demonstrated, very persuasively, in application to all principal binary, some ternary, and one quaternary system. The strict manuscript submission deadlines did not provide the authors with sufficient time to complete all of this important work, but it will undoubtedly be continued elsewhere.

All original assessments presented in this chapter were performed using the MTDATA software developed at the National Physical Laboratory (United Kingdom) with the active participation of one of the authors (Prof. Dinsdale). However, this does not imply that it is better or worse than any other software package, such as Thermo-Calc AB, FactSage, PANDAT, JMatPro, or Open Calphad (OC). In fact, many other thermodynamic calculations were made using the Thermo-Calc software in Chapters 1, 2, and 5.

An important disclaimer is appropriate at that point. Generally, for scientific rigor it is necessary to the critical points that data from binaries (temperatures of the invariant react...
