The microstructural characterization of an superplastic Zn-Al-Ag alloy (72, 24,
and 4 in wt.% respectively) was obtained in this study by using different
spectroscopic analysis techniques; X-Ray Fluorescence (XRF), Scanning Electron
Microscope (SEM) and X-Ray Diffraction (XRD). The super-plasticity characteristic
of the alloy is the main objective to reach for the alloy development followed by
the corrosion resistance improvement in acid rain wither. The superplastic was
guaranteed with fine grain microstructure at the end of the fabrication process.
The result of fabrication process was observed by the identification of
crystallographic phases (morphology, size and distribution) and chemical
composition. The results by XRF show that Zn is the higher proportion element,
in addition the Ag (wt. 4%) addition to Zn-Al base microstructure improves the
grain refinement, as was observed in the SEM characterization. The AgZn 3
intermetallic compound homogeneously dispersed in the Zn-Al solid solution
phase. The size grain observed after the rolling process was less than 10 µm
associated to one of the main characteristics of super-plasticity properties. The
XRD analysis results corroborated the phases presented in the alloy as was
identified with the SEM and EDS characterization.
