INVESTIGATION OF THE EFFECT OF MECHANICAL VIBRATION, COOLING PLATE AND GRAIN REFINEMENT IN SAND MOLDING OF A360 ALUMINUM CASTING ALLOY

Summary/Abstract: The structure that emerges during solidification in aluminum-based casting alloys; It affects the mechanical properties and additional processes may be required to obtain the desired properties. In particular, grain size and shape can be controlled by solidification. It is known that by providing a nondendritic and fine-grained structure in the casting of aluminum alloys, fluidity increases, better feeding and a more non-porous structure are formed, mechanical properties are improved, fatigue resistance and sealing resistance values increase. For this reason, some methods such as the addition of grain refiner (Ti and B based) master alloy to the alloy, casting under mechanical vibration and casting on cooling plate are applied to obtain fine grain structure in the casting of aluminum alloys. In this study; A360 standard Aluminum casting alloy is cast into sand molds prepared with a progressive model designed to create different solidification times. In the experiments, besides the solidification time, the addition of grain refiner, the solidification under mechanical vibration and the effect of casting on the cooling plate on the microstructure were investigated.
