On the use of computational thermodynamics for predicting the precipitation and growth of secondary phases in stainless steels

, 2019
Stainless steels are high-Alloyed, usually with multiple components and often also dual matrix phases, as for duplex stainless steels. This makes predictions and calculations of alloying effects on equilibria and phase transformations a challenge ...

EXPERIMENTAL INVESTIGATIONS OF NITROGEN ALLOYED DUPLEX STAINLESS STEEL IN DRY MILLING PROCESS [PDF]

Journal of Engineering Science and Technology, 2018
Duplex stainless steels are generally more difficult to cut because of their high toughness, low heat conductivity, more strain hardening rate and more built-up edge formation.

ADDITION OF COBALT IN DUPLEX STEEL FUSION ZONE WELDED WITH PULSED Nd:YAG LASER

, 2022
Super duplex stainless steels (SDSS) have a two-phase microstructure, with approximately equal volumetric fractions of ferrite and austenite, giving them excellent mechanical properties and high corrosion resistance.

Lean duplex stainless steel plastically deformed joined by laser welding

, 2017
Duplex stainless steels are preferred in industries where a combination of mechanical properties with higher corrosion resistance is required. Their excellent properties are due to the biphasic microstructure, however, when thermal cycles are applied can

Electrically enhanced plastic deformation of duplex stainless steel UNS S32750

, 2019
It is well known that increasing the temperature softens the materials and increases formability. This could be done in many ways, one of which is by joule heating. In the late fifties it has been observed an enhancement of formability for certain alloys
