Abstract
The transformation of metastableδ-ferrite has been studied in two duplex stainless steel weld metals. The kinetics and the nature of the equilibrium phases produced, depend upon the localized microsegregation of chromium and molybdenum to theδ-ferrite laths in the as-welded state. A transformation model is proposed which suggests that a longer term stability of theδ-ferrite may be achieved by alterations in the basic 316L composition used for the production of submerged arc weld metals.
