Abstract To study the interaction effect of creep and ratchetting for rolled AZ31B magnesium alloy at room temperature, a series stress‐controlled tests were designed. In tests, four loading types with different mean stresses considered, dwell was applied to explore on ratchetting. The test results indicated that sequence is crucial strain evolution. amount twinning/detwinning increased as stress decreased, leading an exhaustion nonbasal slip during ratchetting, then suppressed ductility....
To study the rate effect on ratchetting behavior of rolled AZ31B magnesium (Mg) alloy at 393 K and room temperature, stress-controlled cyclic tension-compression experiments using various load rates were conducted. Four loading amplitudes with different mean stresses used to roles dislocation slipping twinning/detwinning in plastic deformation mechanisms. The Mg was found be temperature dependent, as accumulated strain increased increasing. Furthermore, more apparent than especially under...
Gradient nanotwinned (GNT) metals exhibit extra strengthening and work hardening behaviors, which endow them impressive potentials in engineering applications. The increased strength is attributed to the dense interactions between dislocations boundaries grain interiors. However, a constitutive model elucidating effect currently lacking. Here, we propose theoretical framework describe mechanical response of GNT metals, especially unusual behavior. captures deformation mechanisms coincides...
Abstract Fatigue resistance is crucial for the engineering application of metals. Polycrystalline metals with highly oriented nanotwins have been shown to exhibit a history-independent, stable, and symmetric cyclic response [Pan et al., 2017, Nature 551, pp. 214-217]. However, constitutive model that incorporates deformation mechanism nanotwinned currently lacking. This study aims develop physically based describe plastic under loading parallel twin boundaries. The theoretical analysis...
Abstract To ensure a thermodynamic consistency for constitutive model is higher request modeling the mechanical behaviors of materials. This paper conducts analysis creep-plasticity Al 5083 alloy. The equations are derived from fundamental laws, maintaining rigorous physical basis proposed model. monotonic tensile and creep tests introduced modeling, illustrating rationality accuracy
This paper proposes a theoretical model for the description of tension-compression cyclic plasticity gradient nanostructured (GNS) metals. The grain size effect is considered by introducing Hall–Petch relation local yield stress and strain hardening. With experimentally measured distribution profile, average axial can be calculated cylindrical GNS metal specimens. was verified using experimental data obtained from 316L stainless steel treated surface mechanical rolling treatment (SMRT)....
