Abstract

The effects of Ta on microstructure and mechanical property of Ti-Zr-Cu-Pd-Ta alloys without toxic element were investigated in this paper. The results revealed that with increasing Ta content, the glass-forming ability of examined alloys decreased. Nano-crystalline composites were obtained with 1% and 3% Ta addition. Higher strength and distinct plastic deformation comparing with Ti-Zr-Cu-Pd base alloy were achieved in 1% Ta-containing alloys due to the nano-particles existing in the glassy matrix which inhibit the deformation of shear bands. Dendrite enriched with Ta was also observed in the 5% Ta-containing alloy by SEM. No plastic deformation was observed for 3% and 5% Ta-containing alloys with the high volume fractions of crystallization over 50%.
