Influence of the Solution-Treatment Temperature and Short Aging Times on The Electrochemical Corrosion Behaviour of Uns S32520 Super Duplex Stainless Steel [PDF]
Materials Research, 2019 Sigma phase leads to deterioration of corrosion resistance of super duplex stainless steels (SDSS) and its volume fraction increases as the time which the materials is exposed in determined temperature increases.

Grand Canonical simulations of string tension in elastic surface model
, 2005 We report a numerical evidence that the string tension \sigma can be viewed as an order parameter of the phase transition, which separates the smooth phase from the crumpled one, in the fluid surface model of Helfrich and Polyakov-Kleinert.

Scaling of the largest dynamical barrier in the one-dimensional long-range Ising spin-glass [PDF]
, 2014 The long-range one-dimensional Ising spin-glass with random couplings decaying as $J(r) \propto r^{-\sigma}$ presents a spin-glass phase $T_c(\sigma)>0$ for $0 \leq ...

INFLUENCE OF COLD WORK ON SIGMA PHASE FORMATION IN DUPLEX STAINLESS STEEL [PDF]
Tecnologia em Metalurgia, Materiais e Mineração, 2012 The formation of sigma phase in duplex stainless steels during isothermal aging is widely reported in the literature, but the influence of strain hardening prior to aging on the kinetics of formation of this phase was not a subject of systematic ...

The Xi-Phase and a New Sigma Phase [PDF]
Nature, 1951 Six phases with structures isomorphous with the iron – chromium sigma phase have been reported in binary alloys of the transition elements of the first long period1–3. In addition, Goldschmidt4 has shown that the phase FeMo, stable between 1,180° and 1,540° C., has the same structure.

Enhancements of high order cumulants across the 1st order phase transition boundary
, 2017 In this proceeding, we investigate the dynamical evolution of the $\sigma$ field with a trajectory across the 1st order phase transition boundary, using Langevin dynamics from the linear sigma model. We find the high order cumulants of the $\sigma$ field

On the chiral and deconfinement phase transitions in parity-conserving QED_3 at finite temperature [PDF]
, 2000 We present some results about the interplay between the chiral and deconfinement phase transitions in parity-conserving QED3 (with N flavours of massless 4 component fermions) at finite temperature. Following Grignani et al (Phys. Rev.
