对等温锻造后的ＴｉＡｌ－ＣｒＶ的超塑性进行了研究，发现在适当变形条件下，等温锻造状态的ＴｉＡｌ合金也可表现出较大的超塑性。同时发现，高温氧化对该合金的超塑性能有所影响。在较低温度下低氧压预处理可以改善此合金的抗氧化性和超塑性；在较高温度则显不足。 The superplasticity of TiAl-CrV after isothermal forging has been studied. It is found that the TiAl alloy in isothermal forging state can also exhibit larger superplasticity under the appropriate deformation conditions. It is also found that the high temperature oxidation has an impact on the superplasticity of the alloy. Low oxygen pressure pretreatment at lower temperatures can improve the oxidation resistance and superplasticity of this alloy; however, it is insufficient at higher temperatures.
