Bulk dense Ti-25Nb-3Mo-3Zr-2Sn (TLM) alloy with a discontinuous core-shell structure was successfully synthesized by spark plasma sintering (SPS) of the oxidized TLM powder. A discontinuous core-shell structure is formed, which is mainly attributed to the participation of a phases in 13 matrix near boundaries induced by diffusion of oxygen. The core-shell TLM compact exhibits a yield strength and fracture plasticity approaching 1.36 GPa and 34%, respectively.
