The σ phase which exists in various series of stainless steels is a significant subject in steels
science and engineering. The precipitation of the σ phase is also a widely discussed aspect …

Sigma phase is a deleterious phase which can be formed in duplex stainless steels (DSSs)
during heat treatment, manufacturing, or welding processes, leading to a decrease of …

The precipitation of sigma (σ) phase in the ferritic/austenitic duplex steel (DSS) results in the
deterioration of mechanical intensity and corrosion resistance. After overviewing the …

Optimized double loop electrochemical potentiokinetic reactivation (DL-EPR) in combination
with microstructure observation were successfully applied to study the sensitization of super …

In the present study, effect of solution annealing temperature (1050° C and 1100° C) and
isothermal ageing (700° C: 15min to 6h) on the microstructural changes in 2205 duplex …

In this study, an optimized double loop electrochemical potentiokinetic reactivation (DL-
EPR) test was applied to evaluate the degree of intergranular corrosion (IGC) susceptibility …

Stainless steels subjected to constant load at high temperature, such as under creep
conditions, are known to develop microstructural changes including precipitation of distinct …

This work analyzed the volume fraction of the sigma phase in a superduplex stainless steel
UNS S32760. Two electrochemical testing methodologies were applied for this purpose …

Duplex stainless steels were developed using the synergic effect of the ferritic and austenitic
phases on the mechanical and corrosion properties when they form a microstructure. Due to …
