Paper Title:
Effect of Alloying Elements on the Consolidation and Mechanical Properties of Ti Compacts by SPS
  Abstract

In this study, we focused on the effect of alloying elements (Fe, Mo, and Al) on the consolidation and mechanical properties of Ti compacts. The elemental blended powders is manufactured by spark plasma sintering. The effects of amount of alloying elements and sintering temperature on the relative density and tensile properties of Ti compacts were investigated. The addition of β-stabilizing elements (Fe and Mo) was found significantly improve the densification of Ti compacts, where the sintered density ratio of Ti-5 wt.% Mo specimen was higher than 99.9 %, and Ti-5 wt.% Fe specimen was higher than 99.0 %. On the other hand, addition of Al as α-stabilizing element showed the sintered density rate of Ti-5 wt.% Al specimen was higher than 99.9 %. The tensile property for sintered Ti-5 wt.% Mo specimens had the highest elongation of 16 %. It will be discussed the microstructures and tensile property of the compacts.
