In recent years, CALPHAD has been applied to a broader field of materials science and engineering beyond phase diagram calculation. In this presentation, we will demonstrate the successful application of the CALPHAD approach to understand the precipitation kinetics of multi-component alloys. The PanPrecipitation module of the Pandat software is directly coupled with the thermodynamic calculation engine to obtain the instant update of the thermodynamic information, such as the composition of the matrix phase and the chemical driving force to nucleate the precipitate phases. These properties are then integrated with the Kampmann-Wagner Numerical (KWN) model to predict the microstructural evolution during heat treatment processes. Furthermore, the obtained microstructure information (typically including volume fraction, average particle size, number density and particle size distribution) are used as key inputs for mechanical property model to estimate the mechanical properties of materials. Application examples will be demonstrated using aluminum alloys and magnesium alloys.
