ASTM A923-Practice A application to identify intermetallic phases in a UNS S32750 superduplex welded joint [PDF]
, 2010 Os aços inoxidáveis duplex e superduplex apresentam propriedades superiores aos aços inoxidáveis convencionais. Essa superioridade é baseada na composição química e em uma microestrutura balanceada (aproximadamente 50% de ferrita).

Materials and Corrosion, EarlyView.The localized corrosion behavior of lean duplex stainless steel EN 1.4062 is systematically compared with austenitic and higher‐alloyed duplex grades in natural seawater. A clear resistance ranking is established, highlighting EN 1.4062 as a cost‐effective alternative for limited marine exposure.

SERS‐Based Nano‐ and Microsystems Toward Biomedical Applications
Small, EarlyView.This review provides a current overview of nano‐ and microscale SERS‐based devices, encompassing all aspects from material design to practical applications. We highlight controlled SERS‐active architectures, including patterned substrates, nanorods, microspheres, micromotors, and microneedles, as well as combinations of these microfluidic systems.

steel research international, EarlyView.Heat treatments that alter the proportions of austenite and ferrite phases or induce the precipitation of phases such as sigma in duplex stainless steel UNS S32205 make it more susceptible to pitting and crevice corrosion. However, the effects of these treatments are not always evident when analyzed using the cyclic polarization technique.

steel research international, EarlyView.Laser welding of duplex stainless steel disrupts phase balance, promotes nitride precipitation, and reduces fatigue resistance. Postweld heat treatment restores austenite and dissolves nitrides, but the resulting crystallography and phase morphology still impair fatigue performance.

Low-Temperature Mechanical Behavior of Super Duplex Stainless Steel with Sigma Precipitation [PDF]
Metals, 2015 Experimental studies in various aspects have to be conducted to maintain stable applications of super duplex stainless steels (SDSS) because the occurrence rate of sigma phase, variable temperature and growth direction of sigma phase can influence mechanical performances of SDSS.

steel research international, EarlyView.An accurate moving boundary model for volume diffusion containing boundary conditions from trans‐interface diffusion (TID) simulates the austenite growth during cooling. TID of Cr, Mo, N and Ni enhance growth kinetics. Without TID, compositions of the interface region change, decreasing the driving force for growth and finally causing numerical ...
