摘要：
Ti-50.3Ni (at%) alloy film was prepared by vacuum magnetron sputtering, followed by heat treatment at 460 degrees C for 40 min. The microstructure of the Ni-Ti alloy film was studied using transmission electron microscopy. A nanoscale interwoven structure of B2 and R-phase was observed. The lattice correspondences between B2 and R-phase were analyzed using an electron diffraction pattern. The R-phase can nucleate in the precipitate-free area of the Ni-Ti alloy film at a rapid cooling condition. The full-field strain of B2 and R-phase was mapped through geometric phase analysis technique. The measured strains are consistent with the eigenstrains of the R-phase. (C) 2016 Elsevier Ltd.
