Abstract Scope |
Phase diagrams are frequently referred to as roadmaps for alloy design and process optimization. Although initiated as a method of phase diagram calculation for complicated multicomponent systems, the CALPHAD approach has now been applied to various fields of materials science and engineering including solidification, coating, joining, and phase transformation. This has made the CALPHAD method a key building block of ICME. In this presentation, we will demonstrate that thermodynamic and phase diagram calculations can be integrated with kinetic models for the simulation of diffusion, precipitation, and solidification processes. These simulations can serve as virtual experiments for composition and process optimization, and provide valuable guidance for the design of real key experiments; therefore significantly reduce experimental work load and accelerate materials development. Application examples will be presented for variety of alloys, such as Al-based, Ti-based and Ni-based alloys. The advantages and limitations of the current CALPHAD tools will also be discussed. |
