A shift from ferrous to aluminum alloys for use in automotive engine blocks has reduced the weight of vehicles and has consequently increased fuel economy while reducing harmful emissions. During the casting process of aluminum engine blocks, chilling devices are typically inserted into the cylinders for faster cooling and to allow for a more uniform cooling rate. However, the effects that chillers have on the alloys microstructure (i.e. size, morphology and SDAS) and mechanical properties must be considered. This study characterizes the microstructure throughout an A319 inline six engine block using scanning electron microscopy, energy dispersive spectroscopy and X-ray diffraction. In addition, mechanical testing (i.e. hardness, Charpy, and tensile) have been be performed at various depths along the cylinder web to determine the effects that varying microstructure has on the mechanical properties of the alloy.
