Abstract

The antiphase boundary (APB)-like structure of both 9R and B19 martensites in the Ti-Pd-Fe alloy was investigated by means of transmission electron microscopy. Some APB-like structures with curved and wide contrasts along the (0 0 1)_9Rbasal plane are observed in 9R martensitic plates. The atomic displacement on the APB-like structure reflects the atomic movement stemming from the microdomains formed as a pre-martensitic transformation. The displacement vector of the APB-like structure in the B19 martensite can be expressed as R = 〈1/3 0 -1/2〉_B19. The density of APB-like contrasts increases by the substitution of Fe for Pd in Ti-Pd-Fe alloy.
