Calphad thermodynamic software and databases are important tools for materials and processing development as they can calculate properties outside the equilibrium state. An obstacle to wide application and further development of the Calphad technique is that most software and databases are proprietary and cannot be modified or easily integrated into new applications by users. In this presentation the “Open Calphad”(OC) initative will be described which offers high quality free software and a ﬂexible database structure. The software has an easily extendable facility for users to include modeling of any kind of phase property as function of temperature, pressure and phase constitution of a material. A large number of models for the composition dependence of different kinds of phases have been developed within the Calphad community which will be available within OC. The OC initiative has also the ambition to provide high quality assessments of key binary and ternary systems.
