Alloy Disorder Modeling

Overview

Skills for modeling chemical disorder in alloys: generating representative structures, fitting energy models, and predicting thermodynamic properties (phase diagrams, order-disorder transitions).

Sub-skills

Skill Path Description
SQS Generation sqs-generation/ Generate Special Quasirandom Structures to model random alloys in small periodic cells. Uses icet or pymatgen with Monte Carlo optimization.
Cluster Expansion cluster-expansion/ Fit lattice energy models (cluster expansions) to MACE/QE data. Run Monte Carlo simulations for phase diagrams and order-disorder temperatures.

Typical Workflow

  1. SQS Generation -- Build a representative disordered structure for a target composition.
  2. Relax with MACE or QE -- Obtain ground-state geometry and energy.
  3. Cluster Expansion -- Fit a Hamiltonian across many compositions, then run Monte Carlo for finite-temperature thermodynamics.

Prerequisites

bash
pip install icet sqsgenerator
# Already available: pymatgen, ase, mace-torch, numpy, scipy, matplotlib
