摘要	The formation mechanism of FCC phase on prismatic-basal (PB) interfaces in {1012} < 1011> twin in Zircaloy-4 under cyclic deformation at the strain level of 1.0% was systematically investigated by using transmission electron microscopy. Results showed that {1012} < 1011> twin was presented in alpha-Zr grain and PB inter-faces can be introduced into the twin boundaries. Under cyclic stresses, the emis-sion of 1/3[0110 ] and 1/3 [0110] Shockley partial dislocations would be initiated on the PB interfaces of the twin and slipped symmetrically on every other ( 0001 ) planes of the twin, resulting in the HCP -> FCC phase transformation. Moreover, when the shear stresses were large enough, 1/6 < 112> Shockley partial disloca-tions were activated during cyclic deformation and the formation of { 111 } SFs in FCC phase was presented.
