Abstract Scope Titanium and its alloys are widely used due to their excellent mechanical properties and corrosion resistance, being suitable materials for aircraft and medicine industries. Spark plasma sintering (SPS) is one of the powder metallurgy technologies that has gained attention in research and industry because it offers fast processing and control of the final microstructure, transforming powders into sintered specimens using a mold, generally limited to simple shapes and small dimensions. In this study, an unconventional SPS arrangement was implemented to sinter a metastable beta-Ti15Mo alloy to produce elongated bars of 10 mm in diameter and nearly 100 mm length, overcoming the size limitations in SPS processing. Obtained Ti15Mo bars were processed to study the microstructural-mechanical relationship at different conditions, i.e., SPS-sintered, SPS-sintered + forged, and conventionally prepared alloy. Compact and homogeneous bars with an average grain size of 200 μm were achieved and compared in terms of their mechanical properties.
