Abstract
Investigation of the fracture surface is an effective method in characterizing casting defects . Some data can be collected such as the population of defects and initiation of fracture by means of investigation of fracture surface via a scanning electron microscope (SEM). In this study, tensile test samples from two different 356 aluminium melts that have good and quite bad quality were poured into die and sand moulds under two different conditions: no addition and Al–Ti–B grain refiner addition. After the tensile test, casting defects in fracture surfaces are analysed and classified via SEM. The area fraction of defects (AFD) is created and correlated with bifilm index and tensile properties such as UTS and elongation.
