Characteristics and formation mechanism of Hf inclusions in directionally casted Ni-based superalloy

Characteristics and formation mechanism of Hf inclusions in directionally casted Ni-based superalloy

Scanning electron microscopy, transmission electron microscopy and energy disperse spectrum were used to analyze the morphologies, microstructures and compositions of Hf-rich inclusions in DZ125 and DZ22 Ni-based superalloys. The solidification microstructures of Ni-based alloys with different Hf ad...
