analysis was conducted. From the acquired spectrum Fig.3b, the particle was identified as another Nb precipitate. Prior to this study, it was certain that Nb precipitates as particles above 50nm in steel, but identifying precipitates below this size was not clarified. However, from this analysis conducted on carbon extraction replicas using an FE-SEM, it was proven that Nb can indeed precipitate
Fig.3-2 2-D analysis에서의 온도분포
위의 결과에서 볼 수 있듯이, 온도분포가 x축 값과는 거의 무관하게 y축에만 의존하는 것으로 나타났다. 자세히 비교하면 x=5cm인 지점의 온도가 가장 높고 x=0,10cm인 지점이 가장 낮게 나타나는데, 이 두 값을 1-D numerical analysis로 구한 값과 비교해보았다.
