zn/al is the world’s most commonly used aluminum-zinc alloy, which has a wide range of interesting properties. It can be found in water taps and sanitary fittings, household articles, fashion goods and many other applications.

Despite their low melting temperature, they exhibit interesting combinations of tensile strength, elongation, hardness and ductility. They are also resistant to corrosive environments and have a long service life.

Zinc and aluminum are the most common base metals used in a wide range of mechanical and tribological applications. Their unique combination of excellent ductility, abrasive resistance and superior machinability makes them a preferred choice in most industrial sectors.

In this study, we investigated the feasibility of fabricating bimetallic materials based on Zn-Al eutectoid alloy foams. We also analyzed the IF peak of these foams as a function of the grain size and microstructure.

The IF peak is associated with a diffusive flux on a crystalline boundary between the like-phases of Al/Zinag (Fig. 12). The IF peak of the Zn-Al foams was significantly larger than those of conventional aluminum foams, which may be due to superplastic deformation of the cell walls.

It is possible to achieve high strain rates (>10-1) in Zn-Al eutectoid cladding by powder metallurgy, and to obtain close cell materials with superplastic structure. These superplastic Zn-22mass%Al claddings have higher compressive yield stress and energy absorption capacity than those of ordinary aluminum claddings. They are suitable for shock and impact absorbers, gaskets, dust and fluid filters, engine exhaust mufflers and porous electrodes.
