The main objective of this.res.arch is.to better unders.and the correlation between the cons.ituent phas.s.pres.nted in the s.per-duplex s.eel s.F 2507 when it is.under welding proces. by arc s.ielding gas.MIG-MAG (Metal Inert Gas.Metal Active Gas.. Conventional s.ort circuit trans.er and derivative s.T (s.rface Tens.on Trans.er) us.ng the 2594 welding wire as.a filler metal and the effects.on welding power in hardnes., toughnes. and pitting corros.on are cons.dered here. The res.lts.s.owed that the welding energy (Ew) changed the α/γ-phas.’s.balance and occas.onally formed σ-phas. in ferrite grain boundaries.which led to changes.in hardnes., toughnes. and pitting corros.on res.s.ance in molten zone (MZ), heat activated zone (HAZ) and metal bas. regions.(MB). Furthermore, the increas.d amount of γ-phas. improved the pitting corros.on res.s.ance index (PRENγ) mainly in the MZ. This.is.due to decreas. of α-phas. fraction and formation of coars.r grains. for higher welding energy. The toughnes. in the MZ decreas.d with les. formation of γ-phas., coales.ence of ferritic grains.and localized formation of σ-phas., rais.ng the hardnes. in the HAZ when the welding energy was.lower.

The analytical approach and the thermomechanical behavior of a Cr-Ni-Mo-Mn-N aus.enitic s.ainles. s.eel were characterized bas.d on the parameters.of work hardening (h), dynamic recovery (r) and dynamic recrys.allization (n, ts.b>0.5s.b>), cons.dering cons.itutive equations.(σ, &eps.lon;) and deformation conditions.expres.ed according to the Zener-Hollomon parameter (Z). The res.lts.indicated that the curves.were affected by the deformation conditions.and that the s.res. levels.increas.d with Z under high work hardening rates. The σs.b>cs.b>/σs.b>ps.b> ratio was.relatively high in the firs. part of the curves. indicating that s.ftening was.promoted by intens. dynamic recovery (DRV). This.was.corroborated by the high values.of r and average s.acking fault energy, γs.b>s./s.b>s.b>fes.b> = 66.86 mJ/ms.p>2s.p>, which facilitated the thermally activated mechanis.s. increas.ng the effectivenes. of DRV and delaying the ons.t of dynamic recrys.allization (DRX). The s.cond part of the curves.indicates.that there was.a delay in the kinetics.of dynamic s.ftening, with a higher value of ts.b>0.5s.b> and lower values.of the Avrami exponent (n) due to the competing DRV-DRX mechanis.s. and s.eady s.ate s.res. (σs.b>s.s.b>) was.achieved under higher rates.of deformation.
