Duplex Stainless Steels—Alloys for the 21st Century
Metals, 2021 Duplex stainless steels were first manufactured early in the 20th century, but it was the introduction in the 1970s of the argon-oxygen decarburisation (AOD) steel making process and the addition of nitrogen to these steels, that made the alloys stronger,

Difficulties in the Machining Super Duplex Stainless Steels [PDF]
Műszaki Tudományos Közlemények, 2019 Abstract Super duplex stainless steels are used in increasingly more areas. The machinability of duplex stainless steels is generally poor. We performed dry turning tests on G X2CrNiMoCuN 26-6-3-3 casted superduplex steel, using two different PVD coated cutting inserts. One of them was coated with TiAlN and other with TiAlSiN.

RIETVELD REFINEMENT IN SUPER DUPLEX STAINLESS STEEL [PDF]
Proceedings of the International Symposium on Crystallography, 2015 A X-ray powder diffraction patterns can provide many structural information, for instance, distance between atomic planes, preferential orientation and microstrain/crystallite size.Computer programs based on the Rietveld refinement method are commonly used to extract structural parameters as well as the instrumental parameters.However, many of these ...
