چکیده
Abstract In this work, the influence of tungsten on crevice corrosion resistance three super duplex stainless steels (SDSS) containing 0.0, 0.6, and 2.1 wt.% W was determined. The PD-GS-PD technique used to estimate critical repassivation temperature by performing tests at different temperatures. Additionally, long-term potentiostatic experiments were conducted as a function in natural seawater validate testing. Results showed that improved evidenced higher initiation temperatures, which 7.5–15 °C SDSS than W-free case.

Effect of Secondary Phase Precipitation on the Corrosion Behavior of Duplex Stainless Steels
Duplex stainless steels (DSSs) with austenitic and ferritic phases have been increasingly used for many industrial applications due to their good mechanical properties and corrosion resistance in acidic, caustic and marine environments. However, DSSs are susceptible to intergranular, pitting and stress corrosion in corrosive environments due to the formation of secondary phases. Such phases are...
متن کاملSuper Plasticity of /α Duplex Stainless Steels
In this paper the studies of the two-phase super Plasticity stainless steels is studied. The aim of this study obtained the suitable criteria to thermo-mechanical treatment condition for decrease the microstructure (grain size) and super plasticity property in two-phase stainless steels. Also here we want to show the appropriate ranges of temperature and strain rate used in the process super pl...
متن کاملCorrosion performance of welds in duplex, superduplex and lean duplex stainless steels
To achieve good corrosion resistance in a weld is much more challenging than for plate or sheet material, which has undergone controlled rolling, heat treatment and pickling processes in the steel mill. The choice of weld procedure and parameters, filler metal and shielding gas all play important roles. For duplex and lean duplex grades it is essential to ensure that an adequate amount of auste...
متن کاملCombining the Ohmic Drop and Critical Crevice Solution Approaches to Rationalize Intermediate Attack in Crevice Corrosion
Crevice corrosion material loss is often most severe at intermediate distances into the crevice. This intermediate attack can be rationalized using the ohmic drop model of Pickering if and only if the material in question exhibits active/passive behavior in the crevice environment. Conventional theories that ascribe control of crevice corrosion to chemical changes exclusively cannot rationalize...
