| Abstract Scope |
CALPHAD style modelling is now generally accepted as one of the most powerful tools in materials engineering. It constitutes a major part of the Materials Genome, i.e. the combination of computational tools and databases that serve as a basis for materials design.
In the talk it is reviewed how data representing equilibrium thermodynamics may be applied to non-equilibrium processing. In the CALPHAD method the measured thermodynamic properties are represented by models, yielding mathematical functions that may be extrapolated far outside the equilibrium range. The talk will discuss examples involving highly undercooled liquids and precipitation/dissolution of secondary particles under non-equilibrium conditions.
A major and critical part when building a CALPHAD representation of a materials system is the assessment procedure which will be discussed. This is an area where Ursula Kattner and her coworkers at NIST have played a leading role internationally. |
