| Abstract: | The denitrogenation behavior during vacuum induction melting (VIM) Ni-base superalloy using CaO crucible was studied. The results show that Al addition into the melt has evident effect on denitrogenation ,but Ti addition has adverse effect on denitrogenation. The increase of vacuum level is a powerful way to accelerate the rate of denitrogenation. |
