Abstract Twin boundaries among different variants in Nitinal R-phase were determined using group decomposition theory. It was found that there are four variants in the R-phase. The four variants may form three types of self-accommodation group. The four variants are twin related with {l00}p and {l00}p as twin planes. These results are in good agreement with the experiment data.
