With the decrease of pH, the cathodic current density increased, the passive film became thinner, both Rox and Ret decreased. In acid (pH = 3) NaCl solution, there was only one capacitance arc in Nyquist plot, indicating that the passive film was not stable with the decrease of pH. As ...

and all other properties are generally identical [e, E, density, strength-VS-temperature, KIscc, KIc, etc]. Unsure about fracture mechanic properties [dA-dN etc]. NOTE. As a rule I would NOT specify any 2XXX-T3xxx or -T4xxx Temper due to very poor KIscc [SCC] and EXCO ratings. ...
Low density materials like Al 2024-T351 have found a wide range of applicability due to its capability of bearing high loads. To combat the need of extensive experimental trials to understand the orthogonal machining of Al 2024 T351, Finite element (FE) simulations have been employed. One of ...
Structure of the grains and the grain boundaries, including grain misorientation angle and grain stored energy, based on dislocation density, were probed further. A strong correlation of intergranular attack around grains with higher grain stored energy and therefore high dislocation density was revealed...
1) the maximum peak height of local anodes, inferring the location and intensity of pits, 2) the current density prole at the coating/defect interface (CDI) region and 3) total integrated anodic and cathodic current density values of dened areas in the defect region moving progressively away ...
Moreover, CLP induced higher dislocation density and smaller grain size for the 2024-T351 aluminum alloy. The strengthening mechanism was mainly due to the suppression of dynamic recovery and annihilation of dislocation structure caused by cryogenic temperature being conducive to promoting grain refinement...
Additionally, CLP could induce finer grain and higher-density of dislocation structure, which have an important contribution to improving the nano-hardness and tensile fatigue properties of 2024-T351 aluminum alloy.Li, JingFeng, AixinZhou, JianzhongChen, HuanSun, YunjieTian, XuliangHuang, YuHuang, ...

The experimental results cleared that compared with room temperature laser peening, cryogenic laser peening can induce higher-density of dislocation and smaller-size grain, while the strength and plasticity of the processed 2024-T351 aluminum alloy were simultaneously increased. The analysis results ...
