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 …

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 …

The microstructures and the distribution of alloying elements in alloy and intermetallic
phases forming in a hyper-duplex stainless steel during aging at temperatures in the range …

The aim of this work is to study the hardness of the ferrite, austenite and sigma phases of a
UNS S32760 superduplex stainless steel submitted to different thermal treatments, thus …

The structural integrity of components that operate at elevated temperatures can be
compromised by the precipitation of second phases during long-term service. In industry, the …

In the present study, the hot deformation behavior and softening mechanism of as-cast
S32750 super duplex stainless steel were investigated at low and high strain rates by SEM …

It has been widely reported that the formation of σ phase due to the decomposition of δ-
ferrite at specific conditions plays a negative impact on the mechanical properties of steels …

The aim of this study is to evaluate a new nondestructive method designated as Low-Field
Magnetic Analysis (LFMA) based on the measurement of magnetic flux density for …

The microstructural changes induced by solution treatment of an industrial forged F53 Super
Duplex Stainless Steel alloy were studied, in order to emphasize how component phases …

In this present study, the influence of solution annealing temperature on microstructural
properties of a forged Super Duplex Stainless Steel (SDSS) was investigated by SEM-BSE …
