Fractography is the study of the fracture surface and is concerned with the quantitative and qualitative evaluation of fracture surfaces [1]. It is based on the knowledge of the relationships governing the formation and propagation of fracture areas and is routinely used to determine the cause of failure of forensic engineering or failure analysis [2]. A large majority of casting defects can be detected in the fracture surface. In the technical practice, the formation of a fracture surface represents in most cases the unacceptable stage of mechanical loading or other damage, for instance corrosion damage, of material [3]. Fracture interpretation is a function of the fracture surface condition. The fracture surface contains a wealth of information and it is important to understand them [3] - [9]. Energy-dispersive X-ray spectroscopy (EDS, EDX, or XEDS), is an analytical technique used for the chemical analysis (characterization) of a sample. Accuracy of EDS spectrum can be affected by various factors. The likelihood of an X-ray escaping the specimen, and thus being available to detect and measure depends on the energy of the x-ray and the amount and density of material it has to pass through. This can result in reduce accuracy in inhomogeneous and rough samples. The present paper is focused on the possibility fractography to control quality of the castings made of aluminium AlSi7Mg0.3 Alloy to take chance of the tensile test samples.
