摘　　要：低温Ti-5Al-2.5SnELI的应用主要集中在航空航天及军事工业中,民用的较少。目前国内外对该合金锻态、轧制板材研究的较多,而对该合金常温下铸态组织与性能研究的较少,低温性能研究的更少,缺少大量的数据积累,因而限制了该合金在铸件产品中的应用。今后还要对该合金常温、低温铸态组织性能进行研究,完善并予以推广。Cryogenic Ti-5Al-2.5SnELI was mainly applied to aerospace and munitions industry, and was seldom applied in civilian industry. At present, both at home and aboard, more studies focus mainly on the forging and rolled plate of the alloy, less attention is paid to the as-cast structure and mechanical properties at normal temperature, and much less study on low temperature property. Lacking of the data accumulation limits the application of this alloy to casting products. In the future, the further research should be carried on the as-cast structure and properties of the alloy at room temperature and cryogenic temperature, by which the application of the alloy can be popularized.
