Abstract

Nitrogen solubility and nitride formation in liquid 304 Stainless steel has been measured by sampling method at various temperatures. Also values of thermodynamic functions are determined. Nitrogen solubility in molten 304 Stainless steel is increased with temperature and under the 1atm nitrogen atmosphere, titanium nitride is formed over 0.03wt%Ti in 304Stainless steel. Produced nitride is identified TiN by EDS analysis.

액상의 304스테인레스강중의 질소용해도와 질화물 형성관계를 시료채취법을 이용하여 측정하였으며, 이를 열역학적 함수로 규명하였다. 용융 304스테인레스강의 온도가 높을수록 질소용해도는 증가하였으며, 스테인레스강은 1기압의 질소 분위기하에서 0.3wt.% 이상의 Ti 첨가시 Ti계 질화물이 형성되었다. 또한 스테인레스강중에 Ti 첨가로 형성된 질화물은 TiN으로 판명되었다.
