Direct Observation of the Deformation Mechanism of Twin-Structured Ni NWs under Bending Strain

Metals, 2022
In situ atomic-scale bending tests of twin-structured Ni nanowires were realised using a homemade deformation device. The results showed that the plastic deformation mechanism in twin-structured Ni nanowires depended on the deformation stage.
