MaterialsMap
MaterialsMap is Python package for mapping properties, manufacturing feasibility, and desirability. We focus on guiding materials design graphically while proving API to underlying methods. It utilizes pycalphad and Thermo_Calc for thermodynamic calculations.

Installation
pip (recommended)
feasibility map is suggested to be installed from PyPI.
pip install materialsmap
Development Versions
To install an editable development version with pip:
git clone https://github.com/HUISUN24/materialsmap.git
cd materialsmap
pip install -e .
Upgrading scheil later requires you to run git pull
in this directory.
Run the automated tests using
pytest
Theory
Uses equilibrium and Scheil simulations to allow material design with properties
