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.
