About this document
Effects of Grain Boundaries on Nucleation by Konkman is a document available to read on EtoBox.
This document discusses how grain boundaries and surface defects influence solid-solid and liquid-solid phase transformations. It explains that grain boundaries can facilitate heterogeneous nucleation due to their higher interfacial energy and weaker bonding. Surface defects like pinholes and cavities in container walls also influence metal solidification. The supercooling temperature required for freezing depends on the prior superheating temperature, due to heterogeneous nucleation in cavities. The relati
