“…The lattice parameter of the as-quenched Al-Zn alloys, a (α-Al), in dependence on the zinc composition is shown in Figure 14. These values indicate that the lattice parameter of the α-Al phase of the Al-10%Zn was in a fair agreement with the data given in the literature [10][11][12][13]: a(α-Al) decreased linearly with the increase of zinc content. On the other side, the unit-cell parameter, a(α-Al), of the Al-30%Zn alloy was found to increase.…”

The microstructure of two Al-Zn alloys (with 10 and 30 wt.%Zn content) produced by melting in the high frequency induction furnace were investigated by means of scanning electron microscopy (SEM), energy dispersive X-ray (EDX) spectroscopy, X-ray diffraction (XRD) analysis and the microhardness tests. The results indicate that the presence of iron impurity causes the formation of eutectic (Al,Zn)3Fe in both alloys. The presence of the silicon impurity results in the formation of the phase separation in the Al-10%Zn as-cast alloy. The columnar to equiaxed transition was produced only in the Al-30%Zn as-cast alloy. The Vickers microhardness is higher in the equiaxed zone than in the columnar to equiaxed transition (CET) zone. The presence of iron causes intermetallic phase formation (Al, Fe, Si)3,6Zn in the Al-30%Zn as-cast alloy enabling an increase in the lattice parameter. After a homogenization treatment, the microstructure of Al-Zn treated alloys consists only of α dendrites and stable eutectic phase.

“…It was observed that the presence of iron in the Al-Si alloy causes a slight increase in the lattice parameter [4], enabling more intermetallics to be formed and hence more unconstrained growth is able to occur. [10,11,12,13] Present work…”
