Paper Title:
Investigation on Denitrogenation Technology and Mechanism during VIM Refining Ni-Base Superalloy
  Abstract

The denitrogenation technology and mechanism of a new kind of Ni-base superalloy during vacuum induction melting (VIM) were studied. The nitrogen content could be reduced from 0.0005% to 0.0002% by this technology. The calculated interaction coefficient of Ti with N () is about -0.38, and the activity coefficient of N () is 0.714. The denitrogenation mechanism was discussed through the calculation of the reaction ratio constants and .
