Effect of vibration casting on the properties and microstructure of aluminium alloy castings

Abstract

This research focuses on investigating the impact of mechanical vibration on the solidification process. Previous studies have indicated that solidification plays a crucial role in enhancing the mechanical properties of materials. By incorporating mechanical vibration technology into the solidification process, the quality of castings can be improved by achieving a more uniform microstructure and reducing grain size. In today’s industrial landscape, striving for excellence involves minimising casting defects to zero and enhancing mechanical characteristics. To comprehend the enhancement in microstructure and mechanical properties of castings, this experimental study examines the influence of mechanical mould vibration on the solidification of A356 alloy. The casting process involves a frequency of 50[Formula: see text]Hz. To evaluate the effect of vibration during casting, a comparison is made between a casting without mould vibration and its corresponding mechanical properties. The experimental results clearly demonstrate that employing a vibrating mould during casting leads to grain refinement and a significant improvement in hardness when compared to castings produced without the utilisation of a vibrating mould.
