24 The influence of third phases on the performance of super duplex stainless steel welds

- Yee Ling Siew and Mahendran Sinathuraja
- Description:
- Super duplex stainless steels are composed of equal quantities of ferrite and austenite phases. During welding several other 'third phases' can form in small quantities. These third phases, despite their small volume, can have a profound influence on the performance of these welds in corrosive environments. This project will attempt to identity the third phases present in 'good' and 'bad' welds based on the results of industrial service. The results of this research work will assist in the specification of welding procedures for these materials.
