| Abstract Scope |
Powder metallurgy is an alternative approach of materials preparation. One of its advantages in titanium alloys is a reduction of costs by near net shape processing. Ball milling is able to reduce grain size of powder particles while spark plasma sintering is a suitable method of compaction due to short times and low temperatures sufficient for material compaction which help to preserve achieved refinement.
In this work, a powder of metastable beta titanium alloy Ti-15Mo was cryogenically milled and both initial and milled powder were spark plasma sintered in temperature range 750°C - 850°C for 1 minute to 3 minutes. The effects of milling and sintering parameters on the resulting microstructure and phase composition were studied using SEM and XRD. Microhardness and tensile/compressive tests were performed in order to characterize the mechanical properties. The cryogenic milling causes a decrease of temperature sufficient for material compaction. |
