Atomistic Study on Size Effects in Thermally Induced Martensitic Phase Transformation of NiTi
Microstructure of the NiTi thin films for simulation cell size 8 nm × 8 nm × 2 nm, stabilized at different temperatures (a) K, (b) K, and (c) K, depicting the martensite (B2) phase (in blue) and austenite (B19′) phase (in red). The crystallographic orientations of B2 and B19′ are marked by arrows in the respective phase regions.
