| Abstract: | A quantitative analysis method is developed to study the content of soluble Nb and undissolved Nb in Nb-bearing steels. The test procedure involves chemical dissolution,filtration and Inductively Coupled Plasma Atomic Emission Spectroscopic(ICPAES) analysis.The data by the method prove to match well with the original content,suggesting a potential application in the Nb dissolution and precipitation behaviors during steel reheating and hot deformation processes. |
| Keywords: | Nb-bearing steel soluble Nb undissolved Nb quantitative analysis |
