Presentation Title Counter Gravity Casting of Al Alloys: Microstructure and Properties
Author(s) Konstantinos Georgarakis, Mark Jolly
On-Site Speaker (Planned) Konstantinos Georgarakis
Abstract Scope Counter gravity casting can improve the structural integrity of castings by eliminating defects resulting from the turbulent flow of the molten metal during filling. The Constrained Rapid Induction Melting Single Shot Up-casting (CRIMSON) is an alternative counter-gravity casting approach designed for improving energy efficiency in castings promoting the concept of sustainable foundry. It mainly comprises induction melting of only the sufficient quantity of metal for a single casting, the use of high-quality raw materials and controlled liquid flow (turbulence-free) for counter gravity filling. This work reports on the structure and properties of eutectic and hypoeutectic Al-Si based alloys, produced by CRIMSON casting. Comparisons with gravity sand castings reveal differences in porosity and flow-induced defects. Optical and scanning electron microscopy, X-ray diffraction, X-ray tomography, hardness and tensile tests were employed to study the structure and mechanical properties. The effect of grain refinement in CRIMSON Al-castings is also discussed.
