Analytical model for heat transfer phenomena in cup-cast method

摘要

Cup-cast method is a new method deals with semi-solid slurry preparation recently developed by the authors. In this method, suspension of globular solid particles in molten metal iswhen prepared by controlling the nucleation and growth of solid-particles through the simplest and quickest techniques. In this method, heat transfer phenomenon plays an important role in governing the shape, size, and fraction of solid particles. In the current study, a heat transfer model was proposed and applied to A1-A356 alloy semi-solid slurry preparation. The heat transfer model was Oercnl based on heat balance consideration between cup and slurry and it was in a good agreement with experimental results
