The Theory of Steel Alloying with Gaseous Nitrogen

摘要

The thermodynamic and kinetic laws of nitrogen dissolution in liquid iron alloys are discussed. At normal pressure, nitrogen alloying of steel can be done completely from gaseous phase. The relative rate of nitrogen dissolution in mass transfer mode shouldn' t depend on the pressure of the gaseous phase; the dissolution rate in surface reaction mode will presumable increase with pressure, although the gas usage efficiency will fall.
