This work presents a kinetic study of the sigma phase formation in hyper duplex stainless
steel filler metal. Two sigma phase precipitation kinetics models were developed and …

The corrosion behavior of a new Nb-doped stainless steel (SDSS-Nb) designed by the
CALPHAD method, produced using an open atmosphere process based on recycled …

The failure of a flange for seawater service in the top side of an oil platform was investigated
in this work. The flange was made of superduplex stainless steel UNS S32760, and the …

This study investigates and compares the kinetics of sigma phase formation in established
Super Duplex Stainless Steel (SDSS) and recently developed Hyper Duplex Stainless Steel …

The corrosion and mechanical response produced by quenching in the welded joint of a
new Nb-doped stainless steel designed by the CALPHAD method and produced by open …

Super duplex stainless steel (SDSS) has excellent corrosion resistance and good
mechanical properties. However, the tribological characteristics of these steels reduce their …

The present work aims to review the welding behavior of welded AISI duplex stainless steel
2205 (DSS). DSS has duel phase structure ie austenite and ferrite phases and therefore …

The propensity of duplex stainless steels to form secondary phases that harm their main
properties is a metallurgical problem that continues to be studied. Friction stir welding has …

Precipitation of the intermetallic phases embrittles duplex stainless steels. Currently, most
studies in this subject simulated aging phenomena by first holding the material at different …

The changes of microstructures, element distribution, and comprehensive properties were
studied to explore their interactions with each other, induced by solution treatment of UNS …
