Symposium Low-cost Titanium: 'Affordable Ti'
Presentation Title Preparation of Ti-6Al-4V Alloy Powder by Aluminothermic Reduction
Author(s) Wang Tian, Wang Yaowu
On-Site Speaker (Planned) Wang Tian
Abstract Scope This work introduces a two-stage aluminothermic reduction process for preparing Ti-6Al-4V using Na2TiF6 and Al-V alloy. The pure Ti-6Al-4V could be prepared directly after the first stage reduction. Ti-containing cryolite is also producted after the first stage. In secondary reduction, Ti3+ and Ti-Al intermetallics in Ti-containing cryolite can be reduced to Al-Ti alloy. In consequence, pure cryolite and Al-Ti alloy were obtained. The Al-Ti alloy used as reducing agent as a raw material for the first stage reduction. Cryolite used in aluminum electrolysis. In this process realizes the recovery and reuse of by-product Ti-containing cryolite. In the two-stage aluminothermic reduction process Ti and Al are almost 100% recyclable. The production cost is reduced and green metallurgy and ecological metallurgy are realized.
