Crystallization Behavior of Al(70)Fe(12.5)V(12.5)Nb(5) Amorphous Alloy Formed by Mechanical Alloying

In this study, the formation and crystallization of the Al(70)Fe(12.5)V(12.5)Nb(5) amorphous alloys has been investigated. The addition of Nb enhances the supercooled liquid region and glass forming ability of the Al-Fe-V amorphous alloys. The Al(70)Fe(12.5)V(12.5)Nb(5) amorphous alloy exhibits two...

description In this study, the formation and crystallization of the Al(70)Fe(12.5)V(12.5)Nb(5) amorphous alloys has been investigated. The addition of Nb enhances the supercooled liquid region and glass forming ability of the Al-Fe-V amorphous alloys. The Al(70)Fe(12.5)V(12.5)Nb(5) amorphous alloy exhibits two distinct crystallization steps and a large supercooled liquid region at more than 100 K. Kissinger and Ozawa analyses showed that the two activation energies for crystallization (E(x)) were estimated to be 366.3 ± 23.9 and 380.5 ± 23.9 kJ/mol. Large supercooled liquid regions are expected to gain an application field of Al-based amorphous alloys.
