Meeting 2018 TMS Annual Meeting & Exhibition
Symposium Frontiers in Advanced Functional Thin Films and Nanostructured Materials
Presentation Title Stabilization of Nanocrystalline Grain Size at Elevated Temperatures: Theory and Experiment
Author(s) Carl C Koch
On-Site Speaker (Planned) Carl C Koch
Abstract Scope There are two basic ways in which grain growth can be reduced. The first is the kinetic approach in which the grain boundaries are pinned in various ways to decrease grain boundary mobility. The second is the thermodynamic approach in which the driving force for grain growth is lowered by solute segregation. In the kinetic approach the grain boundary mobility is reduced by various possible mechanisms. The thermodynamic approach depends on introducing solutes that segregate to the grain boundaries such that the free energy of the system reaches a local minimum with respect to grain growth. This talk will review the theories that have been presented for kinetic stabilization and thermodynamic stabilization. The experimental evidence for grain growth in nanocrystalline materials with solute or second phase additions will then be presented and conclusions regarding the efficacy of the stabilization strategies will be discussed.
