The Constrained Rapid Induction Melting Single Shot Up-casting (CRIMSON) is a novel casting approach with significant potential for improving energy efficiency in casting processes and lowering the environmental footprint of foundries. It mainly comprises induction melting of only the precise quantity of metal for a single casting, using high quality raw materials, followed by filling the mould by controlled (turbulence-free) counter gravity flow of molten alloy.
This paper reports, for the first time, the structure and mechanical properties of Al alloys produced by CRIMSON casting. Hypoeutectic Al-Si-Mg and near-eutectic Al-Si alloys, with long and narrow freezing ranges respectively, have been analysed using optical and electron microscopy, X-ray diffraction and X-ray tomography. The mechanical properties of the castings have been studied using tensile tests and micro hardness measurements. The results indicate the high potential of this novel approach to produce castings with high structural integrity and good mechanical properties.
