摘要
介绍了TiAl金属间化合物的室温脆性及高温氧化性,从复相组织化和复合材料化两方面分析了TiAl金属间化合物的强韧化,同时从元素合金化和表面改性两方面分析了其高温氧化性能的改善,进而对未来的研究提出了一些建议。
The properties such as fragility in room-temperature and oxidation in high-temperature of TiAl intermetallic were introduced in this paper. The reinforeed-toughening was analysed from phaze-system- atization and composition. And the oxidation-resistance in high-temperature was also discussed from alloying and surface modification. Thus, some suggestions for research prospect was presented.
