Mg addition inhibits PBS and thus dramatically enhances YS but lowers EL. Specifically, YS of Zn–2.5Ag alloys containing Mg of 0.08%, 0.5%, and 1% is 257.0, 291.8, and 322.6MPa, respectively. The alloys with 0
In the presence of Mg, the addition of Ag has been shown to further improve the strengthening of Al-Cu-Li alloys [23], [28]. In parallel, Zn has been also used as a minor addition to Al-Cu-Li alloys, in combination with Mg [9], [31], [32]. In a recent article, we have ...
The solid solution strengthening of Li, Mg, Al, Mn, Cu and Ag in biodegradable Zn-based alloys is quantitatively investigated by first-principles calculations based on density functional theory. The alloying effect on lattice parameters and elastic constants is determined. Mn is found to have the...
With the rapid development of portable electronics, a powerful, flexible, and durative power supply is urgently demanded. A direct generation of electricity using body or environmental heat by thermoelectricity provides a sustainable solution to this demand, in addition to the technical merits of safety...

Keywords Al-Zn alloy, Nano-silica addition, Mechanical properties, Corrosion resistance, Grain refining Al-Zn alloys were initially designed for lightweight military bridges, but they are currently used in commercial marine engineering applications, ship transportation, and rail transit systems, among...
Body-centred cubic magnesium-lithium-aluminium-base alloys are the lightest of all the structural alloys, with recently developed alloy compositions showing a unique multi-dimensional property profile. By hitherto unrecognised mechanisms, such alloys als

The most widely used are Al–SiC MMCs, made using traditional Al–Cu and Al–Zn alloys as the matrices. In 1983 Toyota introduced the Al–SiC MMC piston for diesel engines and was followed by other manufacturers. Since then additional automotive and aerospace applications have emerged worldwide...
However, the application of Mg alloys is restricted due to their low strength and poor workability. One of the effective ways to improve the strength of Mg alloys is through the addition of rare earth, such as Gd, Y, Zn, and Nd, either individually or in combination [3,4]. The ...
