Grain refinement is a crucial part of processing commercial alloys. Fine equiaxed grains result in improved properties for both cast and wrought alloys. While grain refinement can be accomplished several ways introducing particles or phases which promote nucleation is one of the most effective methods. Discovering new grain refining systems has been a difficult and expensive task. We will demonstrate a new method of searching massive crystallographic data to determine possible grain refining structures using classical nucleation theory. Once candidates are found thermodynamic and kinetic analysis can be used to determine the system viability. The approach is alloy agnostic and enables the discovery of previously unknown or underutilized grain refiners.
