Phase diagram for mixed ternary alloy from evolutionary optimization

چکیده

There is an increasing interest in studying still more complicated magnetic systems. A group of ternary mixed alloys is, among them, a point of interest for as well historical as scientific reasons. The most known material belonging to this group is the famous pigment Prussian blue. The Prussian blue analogues may be characterized by special properties, like the existence of compensation points or different magnetic phases. It is also a computationally hard problem due to a large number of possible combination of states. In this work I present the results of ground state calculations for Prussian blue analog with A lattice occupation 0.66 and p = 0 which is the simplest model. The phase diagram presented show dicrepancies with results presented earlier by other groups coming from the lower total energy obtained in the evolutionary computation.

Ternary Phase Diagram Modeling of Chiral Medetomidine Salts Using NRTL-SAC Model

Experimental determination of solubility and ternary phase diagram of chiral compound are of tedious and time consuming tasks, and in many cases, there is not enough experimental data for different enantiomeric compositions to access the experimental ternary phase diagram. Using thermodynamic models with predictive capability, having less dependency on experimental data, affords a great advanta...

A model for diffusion - controlled solidification of ternary alloys in mushy layers †

We describe a model for non-convecting diffusion-controlled solidification of a ternary (three-component) alloy cooled from below at a planar boundary. The modelling extends previous theory for binary alloy solidification by including a conservation equation for the additional solute component and coupling the conservation equations for heat and species to equilibrium relations from the ternary...

High-throughput screening of shape memory alloy thin-film spreads using nanoindentation

We have demonstrated the utility of nanoindentation as a rapid characterization tool for mapping shape memory alloy compositions in combinatorial thin-film libraries. Nanoindentation was performed on Ni–Mn–Al ternary composition spreads. The indentation hardness and the reduced elastic modulus were mapped across a large fraction of the ternary phase diagram. The large shape memory alloy composi...

Structural investigation of CoMnGe combinatorial epitaxial thin films using microfocused synchrotron X-ray

We discuss important experimental considerations and high-throughput synchrotron-based techniques for structural characterization of binary and ternary composition-spread thin films. We apply these techniques to obtain detailed structural phase diagrams of CoMnGe ternary alloy system. # 2003 Elsevier B.V. All rights reserved. PACS: 61.10.Nz; 07.85.Qe; 68.55.Jk
