Microstructural Transformation in a Root Pass of Superduplex Stainless Steel Multipass Welding

Microstructural Transformation in a Root Pass of Superduplex Stainless Steel Multipass Welding

The microstructure of the root pass in a superduplex stainless steel multipass welding was investigated.Results showed that the welding metal has an austenite matrix with particles of sigma phase formed in the ferrite/austenite interface and intragranularly.Eventhough the filler metal is intended to...
