Abstract：

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,　Δεt/2　equals　0.1%　-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).
