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.
