We derive the evolution equation for a sharp concentric interface in a two-phase elastic solid of spherical shape. The solid is immersed in a reservoir of interstitial species whose diffusion triggers phase transformation. We find that mismatch strain accelerates phase–transformation processes that initiate at the center of the specimen, and slows down those that begin at the boundary.

Abstract
We derive the evolution equation for a sharp concentric interface in a two-phase elastic solid of spherical shape. The solid is immersed in a reservoir of interstitial species whose diffusion triggers phase transformation. We find that mismatch strain accelerates phase–transformation processes that initiate at the center of the specimen, and slows down those that begin at the boundary.File in questo prodotto:
