中文摘要:
      钛合金较高的成本限制了其应用范围,低成本钛合金已成为当前钛合金研究的热点。概述了低成本钛合金国内外的研究现状,着重介绍了宝钛集团研发的低成本钛合金及钛合金的低成本化制备情况,新近研制的BTi31、Ti-3111、BTi-341、BTi-421111、BTi-61111S等低成本钛合金已在汽车、体育休闲等领域获得应用;在钛合金的低成本化制造方面,利用电子束冷床炉熔炼,大量添加返回料,熔炼的扁锭直接轧制板材,显著降低原料成本和加工成本。同时对低成本钛合金的发展方向进行展望,指出今后的研究重点是进一步优化熔炼和加工工艺,提升合金性能水平,提高成材率,拓展应用范围。
英文摘要:
      The high cost of titanium alloy restrict its field of application, therefore, the research of low cost titanium alloy has become a hot spot. In this paper, the research status quo on the low cost titanium alloy at home and abroad is reviewed, and the research and manufacturing technology of the low cost titanium alloy in Baoti Group is introduced emphatically. The recently developed low cost titanium alloy, such as BTi31, Ti-3111, BTi-341, BTi-421111, BTi-61111S and so forth, have already applied in automobile, sports and leisure fields. In the aspect of low cost manufacturing, using electron beam cold hearth melting (EBCHM) and adding heavy return scraps, the slab ingots were melted and then directly rolled plates to obviously reduce raw materials cost and processing cost. Meanwhile, the future development is proposed, and the research emphasis will focus on optimizing the melting and processing technique to promote the performance level and yield for extending the application range of titanium alloy.
