| Abstract Scope |
Materials scientists and engineers rely on good data to make decisions. Where these data do not exist experimentally, they turn to models to fill the gaps and the ICME community has had success in developing Process-structure-property-performance models which allow these gaps to be closed.
However, such models are often developed with limited datasets around narrow composition spaces or temperatures that limit their use. Physics based models often have parameters which, although based in a physical conceptualization, are inferred or hard to measure directly.
For example, CALPHAD models can predict volume fraction, average size of precipitates as well as the sequence of precipitation for different heat treatments and alloy chemistries. However, the interfacial energy is an important parameter for these simulations which is hard to quantify.
This presentation will discuss modeling precipitation and yield strength of IN718 as an example of the advantages and challenges of such approaches. |
