Abstract
In this paper, the role of the calculation of phase diagram (CALPHAD) approach in integrated computational materials engineering (ICME) is discussed. Two examples are used to demonstrate how this approach can be integrated with key experiments and kinetic models in accelerating materials design and development under the framework of ICME. In the first example of developing precious metal modified nickel-based superalloys, phase diagram calculation is integrated with key experiments to quickly locate the composition region with optimum properties. In the second example, thermodynamic calculation is integrated with precipitation simulation to understand the precipitation behaviour of IN100 during a heat treatment process. The simulation clearly demonstrates the formation of primary, secondary and tertiary γ′ in this alloy during the selected heat treatment process.
