The antiphase boundary (APB)-like structure of B33 martensite in a Zr–Co–Pd alloy was investigated by means of conventional transmission electron microscopy and high-angle annular dark-field scanning transmission electron microscopy. The APB-like structure had atomic shifts along both the c-axis on the (010)_B33 basal plane and the b-axis on the (001)_B33 plane. The displacement vector of the APB-like structure could be expressed as R = 〈0, 1/4, 1/2〉_B33. The formation mechanism of the APB-like structure was also elucidated.
