Grain growth behaviour of fine (3 μm) and attrition milled nanocrystalline (32 nm) titanium powers during sintering have been studied. The activation energies of grain growth (Q ^sub g^) in fine titanium were found to be 192.9 and 142.4 kJ/mol at lower and higher temperature ranges, respectively. Th...
