2、V2O5和Al為原料，Mg和Ca作為還原劑的通過多級深度還原法制備Ti6Al4V合金粉體的新方法。與傳統(tǒng)的冶金方法制備Ti6Al4V粉末相比，該方法具有更高的生產(chǎn)效率和更少的環(huán)境污染。自蔓延初級還原實驗的結(jié)果表明，Mg比Ca更適合在此階段作為還原劑，當(dāng)使用Mg作為還原劑時可以得到氧含量為6.74%~16.4%（質(zhì)量分?jǐn)?shù)，下同）的多孔Ti-Al-V-O前驅(qū)體。通過進(jìn)一步的鈣熱深度還原（1173 K下保持3.5 h）可以得到含氧量為0.24%的Ti6Al4V粉體。;Using TiO2, V2O5, and Al as raw materials and Mg and Ca as reducing agents, a novel method for preparing Ti6Al4V alloy powder through multistage deep reduction process was introduced. This new process has higher productivity and less pollution than traditional metallurgical process does. The results of self-propagating primary reduction experiments show that Mg is a more suitable reducing agent than Ca in the specific stage, and the porous Ti-Al-V-O precursor material with 6.74wt%~16.4wt% oxygen can be obtained when the amount of reducing agent Mg is appropriate. The Ti6Al4V powder with 0.24wt% oxygen can be obtained after the further calciothermic deep reduction (holding at 1173 K for 3.5 h)."/>
