melt spinning%Al-Ti-Fe-V alloy%microstructure%structural change
Rapidly solidified Al-2.5Ti-2.5Fe-2.5V alloy was prepared by melt spinning. As-spun and as-annealed microstructures were studied by TEM, HREM, XRD and EDS analysis. The microhardness of the alloy at different annealing temperature was measured. The results show that the as-spun microstructure of the alloy includes four kinds of primary phases: Al11(V,Ti), AlTi3, Al80(V,Ti)20 and Al82(Fe,Ti,V)18 phase. After annealing at 300℃ for 10h, metastable phase Al82(Fe,Ti,V)18 transforms to the stable phase Al13Fe4. After annealing at 400℃ for 10h, the primary phases Al11(V,Ti) and AlTi3 has completely transformed to Al80(V,Ti)20 and Al23Ti9 phase, respectively. The addition of element V increases the microhardness of melt-spun Al-2.5Ti-2.5Fe alloy at elevated temperatures.
