Abstract

In this study, we found a novel lattice correspondence of the B19-B19′ transformation in a Ti-Ni-Cu thin film: (1 1 1)B19′//(0 0 1)B19, [0 1 1]B19′// [1 0 0]B19.· Near the coarse precipitate and the grain boundaries, the B19′ martensite forms with the novel lattice correspondence to product the (1 1 1) type I twinning instead of the usual (0 0 1) compound twinning. Crystallographic analyses show that the novel lattice correspondence results from the local stress concentration.
