摘　　要：采用双剪切方法,研究了钒对TiAl金属间化合物高温变形行为的影响。发现钒能显著提高TiAl化合物低温塑性、降低韧脆转变温度,加钒的TiAl化合物的强度在700℃以下随温度提高而提高。The effect of alloying element V and temperature on the deformation behaviourof TiAl intermetallic compound has been investigated by using double-notch shearing test.Experimental results revealed that the V additive may improve the low temperature ductilityand decrease the ductile-brittle transitional temperature. The strength of the TiAl compoundwith V additive increases with the increase of temperature, up to a peak value at 700℃ ap-proximately.
