Cast aluminum products often contain gas porosity and shrinkage cavities, which can undermine the integrity of these components, particularly in service conditions comprising cyclic loading. Hot Isostatic Pressing (HIPing) should make these products more competitive with their wrought aluminum counterparts. However, is this actually the case? Seek technical literature, which distinguish the fatigue behavior of wrought aluminum alloys with cast aluminum alloys that have been HIPed. Explain your findings.
