Abstract

The antiphase boundary (APB)-like structure of B19 martensite in the Ti-Ni-Pd alloy was investigated by means of conventional transmission electron microscopy and high-angle annular dark-field scanning transmission electron microscopy. Some APB-like structures with wide and curved contrast exhibited shifts along the (010)B19 and (001)B19 planes; that is, it exhibited facets composed of those planes at the atomic level. This atomic displacement reflects the atomic movement stemming from not only martensitic but also a kind of R-phase transformations.
