摘要	The push-pull low cycle fatigue (LCF) behaviors of Ti-48Al-2Mn-2Nb (mole fraction, %), which was formed by centrifugal spray deposition (CSD) under a low pressure vacuum condition, were investigated under the control of total cyclic strain amplitude at ambient temperature. The results show that the available cyclic strain amplitude regions of TiAl alloy are very narrow, Delta epsilon(tau)/2 equals 0.1% similar to 0.25 %, and no cyclic hardening or softening are observed during low cycle fatigue processes. The fatigue lives of CSD samples can be improved by hot isostatic pressing (HIP). The characteristics of dislocation configurations of samples experienced different strain amplitudes have been analyzed by means of transmission electron microscopy (TEM).
