Abstract The activated slip systems in the α-phase of the superplastically de-formed Ti-6Al-4V alloy were analysed by systematic operation method with TEM.The results show that the dominantly activated slip systems in the α-phase are{0110} <21l0> and {0111} <2110>. The {0001} <2110> system as well as the c+αdislocations of b=1/3<1133> will be activated when the deformation temperatureis lowered. Large amounts of TEM observation indicate that the dislocations in theα-phase were mainly activated near the triple grain boundary junctions, α/α grainboundaries, and α/β interfaces.
