Synthesis of nanosized titanium powder by high energy milling

Titanium powders of about 2 μ particle size were subjected to high energy attrition milling in an argon atmosphere. Selecting suitable milling parameters, nanosize (<100 nm) titanium powders were prepared after 15 h of milling. An average particle size of 35 nm was obtained at 30 h of milling after which the particle size stabilized with continuation of milling to 75 h. The powders after milling for various durations were characterized by TEM, ICP and XRD, and these results are reported and discussed.
