The effects of temperature on the chloride-induced corrosion behavior reinforcing steel in simulated sea-sand concrete pore solution are studied by means linear polarization resistance. results show that Ecorr (corrosion potential) and icorr current density) steels and/or chloride concentration (CCl)-related parameters. A correlation between a natural logarithmic CCl observed. It is proved rela...
The hot deformation of TA15 titanium alloy was studied by the compression test on Gleeble-3800 thermal simulation equipment. true stress-strain curves at temperature 1123-1223K and strain rate 0.001-1s -1 were obtained.. results show that flow stress increases with decreasing temperature, as increases. And process is accompanied work hardening dynamic recovery recrystallization. Based alloy, Ar...
A non-Arrhenius model based on the Mittag-Leffler function has been conceived as a basic concept. This approach allows modelling both sub-Arrhenius and super-Arrhenius behaviours giving rise to modified temperature integrals.
In order to realize a better description of plastic flow behavior in the warm deformation process GH4149, GH4169 superalloy was compressed by Gleeble-3800 at temperature 700–900 °C and strain rate 0.01–10 s?1. The constitutive model established using artificial neural network (ANN) Arrhenius equation, accuracy compared. results show that average absolute relative error (AARE) ANN is 4.34%. AARE...
The dielectric relaxation characteristics and mechanism of thermochromic microcapsule-epoxy insulating materials are investigated. Results show that exhibit nonmonotonic characteristics, namely the time gradually increase with raised temperature between about 58℃—66℃, which cannot be depicted by conventional Arrhenius equation or Vogel-Fulcher-Tammann equation. It is proposed characteristic der...
An approach for computing the correlations of species richness values obtained from nested and non-nested sampling schemes is described. The correlations obtained are used to construct species accumulation curves for the Carolina Vegetation Survey data set using the log Arrhenius, Gleason, and Arrhenius models. These models are then used to predict the richness at the 400 m2 scale, a value outs...
In order to develop the high-temperature forging process of high-quality 20MnCr5(SH) gear steel, according physical characteristics hot deformation 20MnCr5(SH), single pass pressing test was carried out in temperature range 930–123 °C and strain rate 0.002–2 s?1 by using a Gleeble-1500D thermal simulator. The stress-strain curve analyzed confirmed microstructure analysis. dynamic recrystallizat...
