| Description |
In this study, the microstructural evolution of Al-Fe-V-Si alloy prepared by mechanical alloying starting from elemental powders was studied. X-ray diffraction results showed that by increasing the milling time, peak shifting and peak broadening of Al reflections occur due to dissolution of alloying elements and grain refinement, respectively. Reduction of Al lattice parameter by increasing the milling time indicates that an Al based solid solutions formed during mechanical alloying and solute concentration increased by increasing the milling time. After 60 h of milling, the microstructure consisted of a nanocrystalline Al solid solutions with a grain size of 19 nm and an internal strain of 0.55 in which Si phase was dispersed. In contrast to previous studies on rapidly solidified Al-Fe-V-Si alloys, there is no formation of trace of Al12(Fe,V)3Si or other intermetallic compounds in the as-milled condition. |
