Abstract Scope |
Hypoeutectic Al-Mg-Si cast alloy has a good balance of strength and ductility. However, coarse block-shaped Mg2Si surrounded by plate-shaped ones are formed depending on cooling rate and chemical composition. This characteristic shape of the particle might control ductility. In-situ observation of damage and fracture process during tensile deformation was conducted by means of synchrotron radiation multi-scale tomography to understand the role of coarse block-shaped Mg2Si particle on fracture in Al-5Mg-2Si casting alloy. It revealed that a block-shaped part that is in the center is definitely fractured when a plate in horizontal spread cracks, because plate-shape parts spread radially surrounding a block-shaped part. It is concluded that block-shaped parts were not the origin of cracking, though they can be frequently observed on fracture surfaces. |
