The purpose of this study was to investigate typical casting defects occurring in investment cast turbofan engine parts made of IN713 C superalloy. SEM and EDS examinations were used to reveal that dross and non-metallic inclusions of a shell mould and crucible material are the most frequently occurring defects. A hypothesis is put forward with regard to the mechanisms of dross formation. EBSD studies were also carried out to reveal grain structure of the elements in question.
