Article Description

Samples were taken from the four main stressed parts of low-silicon cast aluminum alloy steering knuckle castings; their compositions and properties were tested. Microstructure observation and SEM and EDS analysis were performed on the samples, and Image Pro Plus was used to calculate the area fraction of inclusions at each position. The filling and solidification process of casting were simulated for aiding the analysis of inclusion formation. The main purpose of this research is to clarify the formation rules of inclusions in different positions of aluminum alloy castings and take corresponding measures to avoid the occurrence of inclusions, which plays an extremely important role in improving the quality of castings. The results showed that the castings mainly contain oxides such as AlO, MgO, SiO and a small amount of Fe-containing intermetallic compounds. Moreover, the inclusions are affected by the flow rate and cooling rate of the liquid aluminum, and more inclusions are produced above the casting or in the region where the casting wall is thicker.
