摘 要: 鈦合金因具有優(yōu)異的綜合性能在航空航天等領(lǐng)域獲得重要應(yīng)用，但是鈦合金材料的高成本限制了其在海洋工程、兵器、民用等領(lǐng)域的應(yīng)用拓展。鈦合金材料的低成本化制備技術(shù)是目前鈦領(lǐng)域研究的熱點(diǎn)方向之一。本文以每年加工材產(chǎn)量最多的板材、棒材、管材為例，簡要介紹了目前的低成本化制備技術(shù)，包括不含貴重元素的低成本鈦合金研發(fā)技術(shù)、利用鈦殘料的低成本熔煉技術(shù)、一次熔煉技術(shù)，以及鈦板材、棒材、管材高效短流程的低成本化加工技術(shù)等，并提出了鈦合金材料低成本化制備技術(shù)的未來發(fā)展方向。

Abstract:Titanium and its alloys have been utilized in some vital areas like aerospace thanks to their excellent overall properties; however, relatively high manufacturing cost limits extensive applications of titanium alloys in marine, military and civil fields. Therefore, exploiting and developing cost-effective manufacturing approaches for titanium alloys has become the hot spot in titanium research community. In this review, the status in quo of the low-cost manufacturing technologies for industrial plate, bar and tube, which occupied the vast majority of titanium products, were introduced comprehensively. Designing the alloy free of expensive alloying elements, recycling processing scrap for remelting, applying one-step ingot smelting and developing short-process processing routes for profiles were reviewed and discussed thoroughly. Furthermore, based on the review and discussion, the prospects for the development of low-cost titanium manufacturing technology were proposed.
Key words: titanium alloy; cost-effective; manufacturing technology; smelting technology; forging technology; rolling technology
