The CALPHAD method is a powerful tool that initially has been developed for performing thermodynamics and phase equilibria of multicomponent system. Recently the CALPHAD technique is successfully applied to calculations of diffusion mobilities and other phase based properties. However, the method is currently lacking strategies and tools for straightforward implementation of the new models and new data to update databases [1]. Based on evolution and analysis of CALPHAD modelling and multicomponent database development, it is clear that data repositories and effective automation tools are needed for improving the efficiency of future modelling and assessments [2,3] Therefore, current data infrastructure needs and future data mining strategies for CALPHAD type calculations are discussed and presented in this work.
