Phase Transformations Evaluation on a UNS S31803 Duplex Stainless Steel based on Nondestructive Testing


Duplex stainless steel presents special mechanical properties such as, for example, mechanical and corrosion strength, becoming competitive in relation to the other types of stainless steel. One of the great problems of duplex stainless steel microstructural changes study is related to embrittlement above 300oC, with the precipitation of the α’ phase… (More)
