摘要：
It is demonstrated experimentally that using the Council for Scientific and Industrial Research Rheo Casting System and high pressure die casting it is possible to semi-solid process and cast into a shape high purity aluminium without a solidification temperature range. Nucleated embryos grow, coupled with convection by induction during thermal arrest. The semi-solid structure during thermal arrest is captured after rheo-processing and casting. Fundamental solidification principles are used to describe observations of the solid to liquid ratio in the time range during thermal arrest. (C) 2010 Acta Materialia Inc. Published by Elsevier Ltd.
