Prediction of Austenite Retention in Triplex Stainless Steel Weld Metals during Multipass Welding

Abstract

Retention of austenite in multipass weld metals of triplex stainless steels was modeled by considering the inverse phase transformation of martensite to austenite. The amounts of retained austenite in multiply-reheated weld metals were nearly consistent with measured ones. It follows that austenite retention could be predicted during multipass welding.
