| Abstract: |
| The denitrogenation behavior of Ni-base superalloy during vacuum induction melting(VIM) was primarily investigated.The results show that through the best technology,the nitrogen content can be reduced from 0.0011% to 0.0002%.Calculation has been done on the interaction coefficient of Ti to N,and the result is eTiN =-5.79. |
