The antiphase boundary (APB)-like structure of B19′ martensite via R-phase transformation in a Ti-Ni-Fe alloy was investigated by means of transmission electron microscopy. The APB-like structure exhibited shifts along the (0 1 0)B19′, (0 0 1)B19 ′, and (1 0 0)B19′ planes; that is, it exhibited facets composed of those planes at the atomic level. This atomic displacement reflects the atomic movement stemming from the R-phase transformation.
