综述了ＴｉＡｌ金属间化合物的研究进展．介绍ＴｉＡｌ合金室温脆性的解决办法，对其制备和加工的新工艺进行分类评述，并从基础理论研究、制备与加工新技术、类单晶ＴｉＡｌ及ＴｉＡｌ基复合材料的研制等方面指出其今后的研究与开发动向．
The research progress of TiAl intermetallics is reviewed. This paper introduces the solution of room temperature brittleness of TiAl alloy and reviews the preparation and processing of the new technology. It also points out that the new technology of TiAl alloy should be based on the research of basic theory, new technology of preparation and processing, TiAl-based single crystal and TiAl- Research and development trends.
