Molecular Dynamics Modeling of the Effect of Nanotwins on the Superelasticity of Single-Crystalline NiTi Alloys

Figure 7

Snapshots of the nano-NiTi during the compressive loading and the unloading process. The color of the atoms is scaled according to the common neighbor analysis (CNA) pattern [20]. In each snapshot, blue atoms correspond to the B2 structure and gray atoms to the B19′ structure. A few of the outmost surface layers (thickness of 0.5 nm) are not visualized for clarity.
