 - 🟢 🔬 [**AMMAP**](https://github.com/PhasesResearchLab/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.
