Abstract

A new near-β Ti20Nb20Zr alloy was designed using d-electron alloy design and the molybdenum equivalence approach. Ball milling was used to synthesize the Ti20Nb20Zr alloy, and then it was sintered using spark plasma sintering. The structure and microstructure of the designed alloy were studied via x-ray diffraction and scanning electron microscope. The surface analysis was studied using x-ray photoelectron spectroscopy. The result showed that after mechanical alloying, nanocrystalline β-Ti (BCC) and α-Ti (HCP) solid solutions were formed with crystallite sizes of 7.2 nm and 22.7 nm, respectively. The microstructure of the sintered Ti20Nb20Zr alloy consists of a β-Ti region with ultra-fine grains of α-Ti at the grain boundary. Surface analysis revealed that protective oxides of TiO₂, Ti₂O ₃, ZrO₂, and Nb₂O₅ were formed. The developed alloy showed enhanced wettability compared with commercial Ti-6Al-4V alloys.
