This article focuses on aspects important for the commercial production of castings. It discusses the modification process in hypoeutectic and eutectic alloys that differ only in the relative volume fraction of primary aluminum and aluminum-silicon eutectic. The article explains how modification changes porosity formation in a casting. It describes the mechanisms responsible for silicon modification, as well as the modifications and changes in eutectic nucleation and eutectic grain structure. The article reviews the usage of strontium during process steps in foundry practices. The growth of silicon eutectic is described to explain effects ancillary to silicon modification. The article also discusses the effects of elements, such as phosphorus, antimony, bismuth, magnesium, boron, and calcium, on the silicon structure.
