Abstract A crystallographic analysis of the atom positions in the unit cell of the R-phase of the TiNi shape memory alloy has been performed. In addition to a homogeneous shape change the atoms are found to shuffle in the [111]B2 and 〈−211〉B2 directions during the B2 to R-phase transformation. The origin of these shuffles is found to be a complex interaction between 〈110〉〈1–10〉 transverse acoustic and 〈111〉 longitudinal acoustic soft phonon modes.
