Structure and mechanical properties of Al-3Fe rapidly solidified alloy
- Erciyes University, Faculty of Arts and Sciences, Department of Physics, 38039 Kayseri (Turkey)
The Al based Al-3 wt%Fe alloy was prepared by conventionally casting (ingot) and further processed the melt-spinning technique and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) together with energy dispersive spectroscopy (EDS), differential scanning calorimetry (DSC) and the Vickers microhardness tester. The rapidly solidified (RS) binary alloys were composed of supersaturated {alpha}-Al solid solution and finely dispersed intermetallic phases. Experimental results showed that the mechanical properties of RS alloys were enhanced, which can be attributed to significant changes in the microstructure. The dependence of microhardness H{sub V} on the solidification rate (V) was analysed. These results showed that with the increasing values of V, the values of H{sub V} increased.
