Abstract Scope |
Controlling the distribution of alloying elements in aluminum casting and designing new processing practices are supported by an enhanced understanding of the thermodynamics and kinetics of solidification at industrial scales. While the behavior of eutectic forming elements such as copper is well understood, the interactions of peritectic-forming elements such as chromium have received far less attention. Insights and limitations of nucleation models pertinent to industrially-observed cooling rates are explored. This is realized by calculation TTT diagrams using a time dependent nucleation theory. This demonstrates the significance of cooling rates on phase selection in industrially relevant technologies like DC casting and Twin roll casting. To improve future predictions, A possible route to measure thermodynamic and kinetics properties is suggested, for accurate determination of these time dependent nucleation models. |
