Abstract

The effects of Squeeze casting process (SQC) on the as cast microstructure, casting defects and Hardness of A390 aluminum alloy were investigated and compared by sand and permanent mold casting processes. The Squeeze casting was performed using a hydraulic press and 200° C preheated steel die at 120MPa. The microstructural evaluations and Hardness variations were measured. The thermal analyzer technique was used to determine the solidification cooling curve and solidified phases. Result exhibited that the microstructure of the alloy was refined and modified by SQC compered by the sand mold and the permanent mold casting. In addition, the shrinkage defects were severely decreased. The intermetallic phases, the Primary silicon and eutectic silicon particles were refined. The quantitative analyses of microstructures showed that the Squeeze casting decreased the average area of Primary silicon particles and its aspect ratio in amount of 74% and 17% respectively compared with sand casting. Also by using SQC, the Hardness of the alloy increased to 30 and 18% compared to sand and permanent casting methods respectively.
