Oxidation Behavior of Aluminium Granules and Aluminium Alloy Chips During In-Situ Casting

Abstract. A revolutionary casting technique, in-situ melting, eliminates the requirement for pouring and reduces the production of porosities in aluminium (Al) castings, which impacts their melting processes. This study intends to investigate the reaction of aluminium granules and chips made of the alloy (AlSi7Mg) to oxygen during in-situ melting. The granules and chips were heated for 30 minutes in a laboratory furnace at temperatures ranging from 600°C to 850°C using the in-situ casting technique. The physical properties of granules and chips changed from metallic-like silver to greyish-coloured with a matte appearance. The heated samples were analysed for surface morphology and elemental analyses using a Scanning Electron Microscope (SEM) equipped with Energy Dispersive Spectroscopy (EDS). The presence of oxygen on the chip’s surface was disclosed by EDS analysis, and XRD analysis indicated that the chips had been oxidised, resulting in the creation of aluminium oxide (Al2O3).
