Strain rate dependent mechanical properties in single crystal nickel nanowires

(author unknown)



Cheng Peng, Yuan Zhong, and Yang Lu et al.

We measure the strain rate dependence of 0.2% offset yield stress in single-crystal nickel nanowires with diameters ranging from 80 to 300 nm. In situ tensile experiments with strain rates from 10−4 s−1 to 10−2 s−1 were conducted, and the small activation volume (∼10b3, where b is the Burgers vect ... [Appl. Phys.
