Differentiation of specific wear rates of AISI 304 austenitic and AISI 2205 duplex stainless steels at room and high temperatures [PDF]
Heliyon, 2022 Austenitic and duplex stainless steels are used in numerous applications at room and high temperatures. However, their wear behaviour at high temperatures has not yet been sufficiently investigated. Therefore, in this work, wear tests were carried out on

Investigation of Electroplastic Effect on Four Grades of Duplex Stainless Steels [PDF]
Materials (Basel), 2019 Since the late 1950s, an effect of electrical current in addition to joule heating on the deformation of metals called the Electroplastic Effect (EPE) has been known. It is used nowadays in the so-called Electrically Assisted Forming (EAF) processes, but

Some Insight on the Heat-affected Zone Strengthening Mechanisms in Duplex Stainless Steels
Materials Research, 2022 The paper shows that the strengthening mechanisms at the duplex stainless steels' heat-affected zone (HAZ) are sensitive to the volume fractions of the different austenite morphologies and the orientation relationships of these austenite morphologies ...

Phase transformations of the duplex stainless steel UNS S31803 under non-isothermal conditions
Journal of Materials Research and Technology, 2021 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 isothermal conditions and then, quenching down under high cooling ...
