Problem
For a fixed proportion of each phase in a two-phase specimen, how does phase boundary area vary with the shape of the second phase particles? Imagine you have a specimen where all the second phase particles are spheres and another in which all the second phase particles are flat plate-like particles:
1. What would be the difference in phase boundary area for the specimen with spherical particles compared to the one with plate-like particles?
2. What would be the difference in macroscopic physical properties for the specimen with spherical particles compared to the one with plate-like particles?
