Effects of Nitrides Precipitation in Duplex Stainless Steel

CORROSION 2018, 2018
Abstract Duplex Stainless Steels (DSS) are characterized by a dual-phase ferritic-austenitic microstructure and exhibit high corrosion resistance and excellent mechanical properties. However, formation of different types of intermetallic phases and precipitated compounds may occur during fabrication processes such as welding, hot working

Magnetostriction of duplex stainless steels

Materials Science and Technology, 1989
AbstractTo identify suitable non-destructive examination techniques, the saturation magnetostriction of a number of ferritic–austenitic (duplex) stainless steel samples from various manufacturers has been measured using a dilatometric technique. The values were found to lie in two distinct ranges, which suggested that two types of material structure ...

Cavitation erosion of duplex and super duplex stainless steels

Scripta Materialia, 1998
Owing to their excellent corrosion resistance, stainless steels are widely used both in the marine, urban water, chemical and food industries. In addition to the corrosive environment, high fluid flow speeds are always encountered for components used in these industries.

Hardening of Aged Duplex Stainless Steels by Spinodal Decomposition

Microscopy and Microanalysis, 2004
Mechanical properties, such as hardness and impact toughness, of ferrite-containing stainless steels are greatly affected by long-term aging at intermediate temperatures. It is known that the α-α′ spinodal decomposition occurring in the iron–chromium-based ferrite is responsible for this aging susceptibility.

Pitting corrosion of duplex stainless steels

Anti-Corrosion Methods and Materials, 2001
This study showed the complex interactions of alloying elements and their prevailing microstructure on the pitting corrosion. This interaction was illustrated by electrochemical tests of three grades of wrought duplex stainless steels. It was shown that SAF2507 had the highest pitting potential, followed by SAF2205 and SAF2304.

Superplastic Deformation of a Duplex Stainless Steel

Materials Science Forum, 2001
Superplastic behavior of a duplex stainless steel has been studied at 1223 K (950°C) and 1253 K (980°C) for initial strain-rates ranging from 2x10 -4 s -1 to 8x10 -3 s -1 In the given range of temperature, it was observed that the elongation increased as the strain rate decreased The best superplastic conditions were obtained at 1253 K where the ...
