“…Gentet et al [13] observed in LCF tests of AISI 316LN stainless steel that the increase of temperature produced an additional cyclic hardening when the temperature was higher than 548 K, and also considered this effect due to DSA. Enhanced cyclic hardening in the DSA regime has been also reported in LCF tests of various metallic materials, such as duplex stainless steel UNS S32750 [31], near alpha titanium alloy IMI 834 [32], AISI 430F ferritic steel [33], duplex titanium alloy Ti-6-4 [34]. In this study, the abnormal dependence of maximum hardening ratio on temperature can serve as a manifestation of DSA.…”

“…But at 500°C and 600°C, the cyclic hardening phenomena are dominant throughout the low cycle fatigue life. Different authors reported similar remarkable hardening in cyclic stress response of ferritic stainless steels [4,5,12]. This remarkable hardening is considered to be a DSA manifestation.…”

“…Consequently, the properties, such as light weight, high corrosion resistance, and fairly high thermal fatigue resistance are of greater importance in selection of material for high temperature-structure such as in exhaust manifold systems of automotives. So the material parameters and mechanical properties of structural steels in elasto-plastic cyclic behavior at elevated temperature have gained interests in many studies during recent years to replace cast iron, the traditional material for these applications [1][2][3][4][5]. For years, various theoretical constitutive models based on continuum mechanics have been developed for describing the material nonlinearities and allowing accurate modeling of hardening/softening responses under cyclic loading conditions [6][7][8][9][10].…”

In this paper, the tensile and strain-controlled cyclic deformation behavior of a ferritic stainless steel which is developed for the exhaust manifold of automobiles is evaluated experimentally at different temperatures. The effect of temperature on monotonic tensile responses such as yield strength and ultimate tensile strength and the effect of temperature and strain amplitude on the evolution of peak stress are assessed. The objective of this study is also to reveal the mixed mode of cyclic hardening–softening behavior of the ferritic stainless steel under strain-controlled fatigue test conditions. A parameter, critical accumulated plastic strain, is introduced to the constitutive equations for the material for describing the hardening - softening responses. The nonlinear constitutive equations for describing the cyclic responses are implemented into Finite Element code using determined parameters for obtaining numerical simulation. The stabilized hysteretic responses obtained from experiment and predicted from numerical simulation are compared and found to be realistic.

“…Thus, in a 1045 plain carbon steel, where dynamic strain aging is pronounced around 300 o C, Weisse et al [16] demonstrated that fatigue life was a maximum in stress-controlled tests whereas it was a minimum in plastic strain controlled tests. Post deformation microstructural analysis illustrated that dislocations were arranged in dense tangles and in parallel dislocation walls, whereas at other temperatures outside of the DSA regime, dislocation cell structures were primarily observed.Other cyclic deformation studies on ferritic steels [17][18][19] within the DSA regime have confirmed hardening and a reduction in low-cycle fatigue life as well.…”

Stress-controlled uniaxial cyclic tensile tests were conducted on binaryMo-27 at.% Reand Mo-0.3at.% Si solid solutions as a function of temperature and comparedagainst the previously reported cyclic response of pure Mo. The Mo-27at.%Re alloy with a recrystallized grain size of ~30 m was evaluated in the temperature range 25 o C to 800°Cat R=0.1 and stress range that was 80% of the ultimate tensile strength (UTS);a peak in fatigue life was observed between 300°C and 500°C. The decrease in fatigue life at the higher temperatures of 700°C and 800°C is attributed to dynamic strain aging.Transmission electron microscopy of the cyclically-deformed alloy revealed parallel bands of dislocation at room temperaturethat transitioned to a uniform cell structure at 500 o C and back to orthogonal planar arrays at800 o C. The as-extruded Mo-0.3at.%Si alloy was evaluated from 25 o C to 1200°C and showed superior fatigue life and ratcheting strain resistance as compared to pure Mo and the Mo-27at.% Re alloy(within the temperature range where data were available for comparison). The superior resistanceis attributed to the high density of dislocations within the material in this mostly unrecrystallized state rather than Si in solid solution. Above 800 o C, the ratcheting strain increases and fatigue lifedecreases rapidly with increasing temperature and is associated with dynamic recovery.
