The stress-strain data of 20MnNiMo alloy were collected from a series of hot compressions on Gleeble-1500 thermal-mechanical simulator in the temperature range of 1173 ∼ 1473 K and strain rate range of 0.01 ∼ 10 s(-1). Based on the experimental data, the improved Arrhenius-type constitutive model and the artificial neural network (ANN) model were established to predict the high temperature flow...

We consider an open two-level system driven by a piecewise constant periodic field and described by a rate equation with Fermi, Bose, and Arrhenius rates, respectively. We derive an analytical expression for the generating function and large deviation function of the work performed by the field and show that a work fluctuation theorem holds.

The frequency of abdominal peristaltic locomotor waves in tent caterpillars during vertical ascension is controlled by the temperature according to the equation of Arrhenius. The constant micro (temperature characteristic) has the value 12,200 calories, agreeing quantitatively with the value obtained for a number of other (non-respiratory) rhythmic neuromuscular movements among arthropods.

This research investigated how the variation of temperature and shear rate affects viscosity ethanol gel propellants that use methyl cellulose as gellant and, in parts, boron energetic additive. Using a rotational viscometer cone-and-plate configuration, propellant data was recorded across range temperatures applied rates. The temperaturedependence modelled using an Arrhenius-type equation. For...

The ionic conductivity of the superionic conductor Sr0.7La0.15Lu0.15F2.3 with fluorite-type structure (type CaF2, sp. gr. Fm-3m) had measured by impedance spectroscopy in temperature range 385–794 K. Bulk crystals a three-component solid solution (lattice parameter = 5.7726(1) A) obtained from melt directed crystallization technique. Temperature dependence σdc(T) satisfies Arrhenius–Frenkel equ...

The most commonly used equation that is to describe the temperature dependency of chemical reaction rates Arrhenius equation. impact on grease life usually not described using but by a more “contemplative” In this note equations will be compared and it shown these are almost identical despite apparent “engineering character” This should remove any doubts use

catalysts with the formula of laco(1+x)o(3+δ), where 0 ≤ x ≤ 1, were studied for oxidation of co and c2h6 in a synthetic exhaust gas, comprising 6.0 % co and 0.2 % c2h6 in ar. ethane was selected as a model for hydrocarbons in the exhaust gas. the performance of catalysts is correlated to their properties, particularly their redox in oxidizing and reducing atmospheres. xrd patterns show perovsk...
