Abstract

The microstructural change during a compression-tension thermomechanical cyclic loading of an Al-Si-Cu-Mg alloy casting is investigated. Although the thermomechanical fatigue loading was applied after the alloy was tempered to the T6 peak aging condition, preferential orientation of precipitates is observed together with anisotropy in deformation behavior. The precipitates are observed to align perpendicular to a compressive stress during heating. The effects of preferential orientation are also discussed on the basis of a model analysis.
