| Abstract | Ti-2 at%Fe-10 at%Si amorphous powder was synthesized by mechanical alloying (MA) of elementary Ti, Fe and Si powders using planetary ball milling for 1440 ks. Crystallization temperature of the obtained amorphous powder was ca. 830K. Ti-2 at%Fe-10 at%Si amorphous powder was consolidated using a pulsed current sintering (PCS) process at a die temperature of 773K under a pressure of 372MPa. Then the compact was densified at a die temperature between 743K and 763K, which is around the crystallization temperature of the amorphous phase. The obtained Ti-2 at%Fe-10 at%Si alloy consists mainly of nanocrystalline -Ti phase. The compressive strength of the nanocrystalline compact at room temperature was more than 1.7GPa, much higher than that of a commercial Ti-6mass%Al-4mass%V alloy. |
