摘要：
Synthesis of nanocrystalline Ti-6Al-4V was explored using mechanochemical processing. The reaction mixture was comprised of CaH2, Mg powder, anhydrous AlCl3, anhydrous VCl3, and TiCl4. The milled powder (reaction product) primarily consisted of nanocrystalline alloy hydride having a composition (Ti-6Al-4V)H1.942, along with MgCl2 and CaCl2 as by-products. Aqueous solutions of nitric acid, sulfuric acid, and 1 pct sodium sulfite were found to be very effective in leaching of the chlorides from the milled powder. The (Ti-6Al-4V)H1.942 on dehydrogenation at 375°C resulted in nanocrystalline Ti-6Al-4V alloy powder.
