摘　　要：Ti3Al基金属间化合物由于其优异的高温性能而成为一种很重要的航空材料。本文详细评述了Ti3Al基金属间化合物变形行为的研究进展，其中包括D0(19)型结构有序合金的位错特点，滑移系的P－N力理论模型以及合金变形行为方面的研究现状。Ti2Al-based intermetallic compounds are becoming one of the most important aerospace materials because of their strong potential for high-temperature applications. In this paper, recent developments in deformation behavior of Ti3Al-based alloys are reviewed in detail, including the dislocation characteristic of DO19 structural ordered alloys, theoretical models of P-N force of slip system and the advancemnt in deformation behavior of the alloys.
