An investigation on the microstructure and mechanical properties of spray-deposited Al–8.5Fe–1.1V–1.9Si alloy

In this study, Al–8.5Fe–1.1V–1.9Si alloy was synthesized by the spray-atomization and -deposition technique. The microstructure and mechanical properties of the alloy were studied using transmission electron microscopy (TEM), X-ray diffraction (XRD), and tensile tests. The secondary phases in the microstructure of the spray-deposited alloy were examined. The tensile test results indicate that the spray-deposited Al–8.5Fe–1.1V–1.9Si alloy both at room and elevated temperature displays superior tensile strength due to the presence of the thermally stable Al12(Fe,V)3Si particles.
