Abstract Scope |
Over the past decades, CALPHAD has proved successful as a helpful tool to understand the "coupling of phase diagrams and thermochemistry". Some prominent practical advantages of this semi-emprical approach are: (i) cross checking of internal consistencies for different types of materials data, (ii) enabling computer calculated extrapolations to multicomponent systems not known by experiments, and (iii) accelerating materials research and development by combining with e.g. phase field and finite element methods, respectively. Nowadays, still experimental analytical data provide major input for thermodynamic optimization to establish reliable analytical descriptions for the Gibbs free energies for all system phases. This presentation will introduce examples for using advanced materials analytics in multicomponent engineering systems (battery calorimetry, flash DSC, high-resolution analytics) to efficiently build up CALPHAD-type optimized databases for application-oriented calculations. Examples from lithium-ion batteries research, refractory alloys development and metal-ceramic composites area are presented. |
