【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。
[Abstract]:The high cost of titanium alloy limits its application scope, and low cost titanium alloy has become the hot spot of titanium alloy research at present. The research status of low cost titanium alloy at home and abroad is summarized. The low cost titanium alloy developed by Baoti Group and the low cost preparation of titanium alloy are introduced in this paper. The recently developed low cost titanium alloys, such as BTi 31U Ti-3111N BTi-341U BTi-421111BTi-61111S, have been applied in the field of automobile, sports and leisure, and in the field of low cost manufacture of titanium alloy. By using electron beam cold bed furnace melting, adding a large amount of return material, the flat ingot directly rolled the sheet metal, the cost of raw material and the processing cost are significantly reduced. At the same time, the development direction of low cost titanium alloy is prospected. It is pointed out that the emphasis of the future research is to further optimize the melting and processing technology, to improve the alloy properties, to increase the rate of finished materials and to expand the scope of application.
