摘要:

鈦合金因具有比強度高、耐蝕、耐低溫、無磁、生物相容性好等優異的綜合性能，在航空、航天、海洋工程、石油化工、民用等國民經濟各行各業得到大量應用，受到眾多行業的高度重視。近5年國內鈦行業工藝、技術和產品等得到提升，取得眾多成果。簡要綜述了近5年國內鈦合金材料研發取得的主要進展，如開發的多種鈦合金材料成功應用于我國重要工程，鈦合金的熔煉技術、鍛造技術、板材制備技術、大口徑鈦及鈦合金無縫管材及彎管制備技術、鈦合金型材及深加工制品制備技術等得到明顯提升，創新研制了滿足用戶要求的新合金并開展了眾多的應用基礎研究等，最后指出了存在的問題和發展方向。

Abstract:

Because of their excellent comprehensive properties, such as high specific strength, good corrosion resistance, low temperature resistance, nonmagnetic property and good biocompatibility, Ti-alloys are widely used in aviation, space flight, marine, chemical engineering fields, and so on. Ti-alloys have been paid more attention. In recent 5 years, national titanium industry’s technologies, techniques and products have been improved and many achievements have been attained. This paper briefly introduces the main progresses of R&D on Ti-alloy materials in recent 5 years in China, for example, many designations of Ti-alloys have been used for national key engineering projects, and their melting technology, forging technology, plate rolling technology, processing technology for big diameter seamless tubes, structural sections and deep processing products have been improved greatly. Several new Ti-alloys have been designed and developed to meet the requirements and many basic researches for applications are undergoing. Finally, the problems existed and developing directions are proposed.
