| Abstract: | A new method of determination of the fend contents of several types of duplexstainless steel welds by an computerized image analyser was developed in this paper. The results showed that this method can give fast, accurate and reproducible ferrite contentdetermination and is more advanced than the methods of point count and extended ferritenumber system and promise that this method could form the basis for a standard procedurefor rapid ferrite content determination in duplex stainless steels.The influence of heat input onferrite content was also investigated in this study. |
