Thermodynamic and kinetic databases are indispensable in providing multicomponent phase diagram and phase transformation data for materials design and process optimization. The recent progress in developing TCCU3 and MOBCU3, the thermodynamic and kinetic databases consisting of 30 elements for copper alloys, is presented in this work. The databases have been validated by ensuring their predictive capability in many multicomponent and industrial alloys following the verification of the assessed binary and ternary systems. It is shown that TCCU3 also contains molar volume data, which can be used to calculate density, coefficient of thermal expansion, and lattice parameter, etc. Applications of these databases in simulating solidification, homogenization, and aging processes are demonstrated and discussed. A case study on high/medium entropy brasses is given in the end to highlight the power of the databases in combination with adequate models.
