🟢 ✅ pycalphad - (@richardotis now at NASA JPL) - is a free and open-source Python library for designing thermodynamic models, calculating phase diagrams and investigating phase equilibria within the CALPHAD method. It provides routines for reading Thermo-Calc TDB files and for solving the multi-component, multi-phase Gibbs energy minimization problem.
-
🟢 ✅ ESPEI - (@bocklund now at LLNL) - Extensible Self-optimizing Phase Equilibria Infrastructure, is a tool for creating CALPHAD databases and evaluating the uncertanity of CALPHAD models. The purpose of ESPEI is to be both a user tool for fitting state-of-the-art CALPHAD-type models and to be a research platform for developing methods for fitting and uncertainty quantification.
-
🟢 ✅ pySIPFENN - py(Structure-Informed Prediction of Formation Energy using Neural Networks) allows for easy prediction of formation energy out-of-the-box (🟢✅) and using small-dataset ML through transfer learning-based adjustment of models to new materials (🟠) and properties (🔴).
-
🟢 ✅ ULTERA-contribute - A template data-repository with growing number of embedded automations for alloy dataset handling, including data validation and abnormality detection. For now, hardcoded for ULTERA (ultera.org) contributions, but will soon be generalized.
-
🟢 ✅ nimplex - NIM simPLEX is a concise high-performance scientific Nim library (with CLI and Python binding) providing samplings, uniform grids, traversal graphs, and more in compositional (simplex) spaces, where traditional methods designed for euclidean spaces fail or otherwise become impractical. We use it primarily for designing Functionally Graded Materials (FGM) but it target applications also include a wide range disciplines including financial modeling.
-
🟢 ✅ nimcso - NIM Composition Space Optimization is a high-performance tool leveraging metaprogramming to implement several methods for selecting components (data dimensions) in compositional datasets, as to optimize the data availability and density for applications such as machine learning.
-
🟢 🔬 AMMAP - a CALPHAD-based tool helping avoid the formation of undesired phases and designing optimal composition pathway to join dissimilar materials. It provides a comprehensive understanding of the phase formation process during manufacturing processes through prediction of both equilibrium and non-equilibrium phases. Utilizes Nimplex to efficiently generate and explore multicomponent multidimensional space.
-
🟢 🔬 MaterialsMap - **Materials map is a CALPHAD-based tool helping avoid the formation of undesired phases and designing optimal composition pathway to join dissimilar materials. It provides a comprehensive understanding of the phase formation process during manufacturing processes through prediction of both equilibrium and non-equilibrium phases.
-
🟢 🔬 PyQAlloy - Python toolset for Quality of Alloys data is aimed at curating large alloy datasets, and in particular error prone ones like HEA/MPEA/CCA ones, through multi-scope detection of a number of abnormal patterns prompting re-verification.
-
🟢 🏗 heaGAN - (codeveloped with Reinhart Group) - A demonstrator workflow for (1) training surrogate models for alloy design and (2) generating novel high entropy alloys design with condditional Generative Adversarial Networks. You can run it in the cloud and download your trained models.

Development:
-
🤏 🟢 🔬 optimade-python-tools-mpdd - fork of Materials-Consortia/optimade-python-tools by @ml-evs; tuned to the needs of MPDD and, more generally, other very large memory IO limited materials databases.
-
🤏 🟢 ✅ pqam-dparamhu2021 - PyQAlloy-compatible Model for alloy D Parameter prediction based on Yong-Jie Hu's 2021 literature model (in R) which has been optimized for high-throughput and wrapped in Python.
-
🤏 🟢 ✅ pqam_RMSADTandoc2023 - PyQAlloy-compatible Model for alloy Root Mean Squared Atomic Displacement prediction is a lightweight fork of Christopher Tandoc's 2023 literature model.
-
🟠/🟢 ✅ MPDD (server & tools) - Material-Property-Descriptor Database is an atomistic data processing infrastructure allowing decentralized featurization (calculation of descriptors) and rapid machine learning model deployment on millions of DFT-relaxed configurations. Data is openly served through OPTIMADE API at mpddoptimade.phaseslab.com, but the high-throughput API and source code for server and client are kept internal for now.
-
🟠 ✅ crystALL - a set of tools to leverage speed of new SIPFENN featurizers and millions of structures in MPDD for prediction of crystal structure applicable to ALL chemistries. Demonstrated, e.g., in:
-
🟠 🏗 pqam-dparamkrajewski2023 - Transfer-learnig based prediction of intrinsic ductility of refractory alloys.
-
🟠 🏗 [Automation of thermodynamic modelling package] The package aims to develop an automated workflow for CALPHAD-based thermodynamic modeling using four Python based open-source tools: PyCalphad for equilibrium thermodynamic calculations, ESPEI for automation of CALPHAD modeling, DFTTK for density functional theory (DFT) based first-principles calculations, and PySIPFENN for machine learning predictions of thermodynamic properties.
