Abstract
Detailed descriptions of complex microstructures are necessary for detailed understanding of their production and consequences. However, there is no consensus on how to characterize microstructures with even three phases. Invariant ternary eutectics have greater complexity than binary eutectics, require more variables to completely describe, may change morphology due to processing conditions, and are deceptively difficult to characterize automatically. For these reasons, a program has been developed which can partition a ternary image into regions of its three phases (using a segmentation and correction process prescribed by the user), then return an assortment of measurements characterizing the microstructure. These measurements have already provided new information about microstructure evolution in directionally solidified invariant Al-Ag-Cu following a solidification velocity change. Results from this program, combined with the findings of a previous study, suggest a relationship between solidification velocity and phase volume fraction in directionally solidified invariant eutectics.
