In a complex-shaped parts, machining is employed before and after heat-treatment. Residual stress is introduced in the production process influenced by various factors, and it might induce several defects in processing or fatigue fracture during service. In-situ neutron diffraction during tensile loading was performed for two kinds of Al-Si alloys, forged-solutioned and die-cast, to determine stress partitioning between Si and Al as well as among [hkl] family grains. Such phase or intergranular stresses are important to evaluate residual stresses in a component.
