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
