Welding Metallurgy - an overview | ScienceDirect Topics

Welding metallurgy has played a key role in the alloy development of duplex stainless steels. The earliest grades had high carbon contents and tended to form a ferrite-rich heat affected zone (HAZ). Although some austenite reformation occurred due to these high carbon levels, this also led to carbide precipitation and a loss in intergranular
