Abstract
The paper presents investigations concerning causes of non-metallic inclusions forming in castings made of nickel-base superalloys. The most common reason of inclusions forming is erosion and thermal decomposition of crucibles and molds by the action of liquid alloy. In case of superalloys containing reactive elements (Hf), many reactions at the alloy-crucible and alloy-mold interfaces take place.
