TL;DR: In this article, a precipitation-hardenable wrought magnesium alloy based on the Mg-Zn system with an excellent combination of high tensile yield strength, good ductility and low tensile-compression anisotropy has been developed.

TL;DR: In this paper, the peak hardness of alloy powders is associated with the concentration of the alloying element initially in solid solution in the powders and the strengthening observed is interpreted in terms of theories of precipitation and dispersion strengthening.

TL;DR: It is shown that the nanocrystalline Zn exhibits a high cycling stability even after 50 deposition/stripping cycles and this strategy of introducing an inorganic metal salt in ionic liquid electrolytes can be considered as an efficient way to obtain dendrite-free zinc.
Abstract: Metallic zinc is a promising anode material for rechargeable Zn-based batteries. However, the dendritic growth of zinc has prevented practical applications. Herein it is demonstrated that dendrite-free zinc deposits with a nanocrystalline structure can be obtained by using nickel triflate as an additive in a zinc triflate containing ionic liquid. The formation of a thin layer of Zn-Ni alloy (η- and γ-phases) on the surface and in the initial stages of deposition along with the formation of an interfacial layer on the electrode strongly affect the nucleation and growth of zinc. A well-defined and uniform nanocrystalline zinc deposit with particle sizes of about 25 nm was obtained in the presence of Ni(II) . Further, it is shown that the nanocrystalline Zn exhibits a high cycling stability even after 50 deposition/stripping cycles. This strategy of introducing an inorganic metal salt in ionic liquid electrolytes can be considered as an efficient way to obtain dendrite-free zinc.

01 Oct 1973TL;DR: In this paper, chemical analyses of individual precipitates found during the initial stages of precipitation of copper from Fe-1.4 at 500°C were made with the FIM-atom probe.
Abstract: Chemical analyses of individual precipitates found during the initial stages of precipitation of copper from Fe-1.4 at. pct Cu at 500°C were made with the FIM-atom probe. Precipitates as small as 8 × l0−8cm in diam were analyzed. The results indicate that the precipitate nuclei contain much less copper than the equilibrium e phase and that most of the particle-matrix boundaries are less than 10−7 cm wide. The average copper content of the precipitates increases with aging time until well after the alloy reaches its peak strength. Thermodynamic calculations show that it is reasonable to expect the precipitate compositions that were experimentally observed.
