Book Description
In this work, a self-consistent thermodynamic database for the Mg-Al-Ca-Sr system using the modified quasichemical model has been constructed. The thermodynamic description of the quaternary system was established by combining the thermodynamic descriptions of the constituent binary and ternary sub-systems. The Mg-Al-Ca and Mg-Al-Sr systems were investigated by combining thermodynamic modeling and experimental investigation. The experimental investigation has been performed using DSC, XRD, SEM and EPMA. Also, isothermal sections at 300°C and 400°C were constructed for the Mg-Al-Ca and Mg-Al-Sr systems. In the Mg-Al-Sr system, six ternary solubilities of the binary compounds extended into the ternary system have been found and denoted as (Mg 17 Sr 2), (Mg 23 Sr 6), (Mg 38 Sr 9), (Mg 2 Sr), (Al 4 Sr) and (Al 2 Sr). The reported ternary compound in the literature (Mg 58 Al 38 Sr 4) has been observed in this work. In the Mg-Al-Ca system, three binary compounds were found to dissolve the third component in the ternary system and were denoted as (Al 2 Ca), (Al 3 Ca 8), and (Mg 2 Ca). The ternary compound (C36) reported in the literature has been confirmed. A comparison between the calculated liquidus projection of the Mg-Ca-Sr system using the modified quasichemical model and random solution model has been presented. It was found that while the random solution model agrees well with the experimental phase diagram, the modified quasichemical model gives better agreement with the experimental thermodynamic data and the experimental phase diagram. Liquidus projection of the Al-Ca-Sr system was calculated using the modified quasichemical model and combined with the other three ternaries in one database for the Mg-Al-Ca-Sr system.

Book Description
Magnesium and Its Alloys: Technology and Applications covers a wide scope of topics related to magnesium science and engineering, from manufacturing and production to finishing and applications. This handbook contains thirteen chapters, each contributed by experts in their respective fields, and presents a broad spectrum of new information on pure magnesium, magnesium alloys, and magnesium matrix MgMCs composites. It covers such topics as computational thermodynamics, modern Mg-alloys with enhanced creep or fatigue properties, cutting-edge approaches to melt treating (grain refinement, micro-alloying, and the resulting solidification and growth), coatings, surface engineering, environmental protection (recycling and green energy storage and production), as well as biomedical applications. Aimed at researchers, professionals, and graduate students, the book conveys comprehensive and cutting-edge knowledge on magnesium alloys. It is especially useful to those in the fields of materials engineering, mechanical engineering, manufacturing engineering, and metallurgy.

Book Description
This book compiles selected publications authored or co-authored by the editor to present a comprehensive understanding of following topics: (1) density functional theory and CALPHAD modeling; (2) computational tools; and (3) applications of computational thermodynamics. It is noted that while entropy at one scale is well represented by standard statistical mechanics in terms of probability of individual configurations at that scale, the theory capable of counting total entropy of a system from different scales is lacking. The zentropy theory provides a nested form for configurational entropy enabling multiscale modeling to account for disorder and fluctuations from the electronic scale based on quantum mechanics to the experimental scale based on statistical mechanics using free energies of individual configurations rather than their total energies in standard statistical mechanics. The predictions from the zentropy theory demonstrate remarkable agreements with experimental observations for magnetic transitions and associated emergent behaviors of strongly correlated metals and oxides, including singularity and instability at critical points and positive and negative thermal expansions, without the need of additional truncated models and fitting model parameters beyond density function theory. This paves the way to provide the predicted phase equilibrium data for high throughput predictive CALPHAD modeling of complex material systems, and those individual configurations may thus be considered as the genomic building blocks of individual phases in the spirit of Materials Genome®.
