A study was conducted to determine how the mechanical properties of an A356-T6 Aluminum alloy are affected by solidification time. Solidification time has been found to have a large effect on the microstructure, especially in terms of the size of the SDAS as well as the size and distribution of porosity. Solidification time also has a large effect on the ultimate tensile strength, ductility, and fatigue properties of A356-T6 Al. Comparisons between porosity-containing (“As-Cast) and porosity-free (“As-Cast + HIP”) samples revealed that the presence of porosity had a dramatic effect on fatigue life; tensile properties remained unaffected.
