Fig. 1: Size dependence of yield strength in Ag NWs and Pt NWs.
From: Atomistic processes of surface-diffusion-induced abnormal softening in nanoscale metallic crystals
In situ tensile straining of < 112 > -oriented Ag NWs with different sample diameters were performed at strain rates of ~ 10−2 s−1 (green points) and ~ 10−3 s−1 (red points). Pt NWs were loaded along <112 > -orientation at a strain rate of ~ 10−3 (blue points). The blue, red and green lines represent the tendency of the strength-size relationship in Pt NWs under a strain rate of ~ 10−3 s−1 and Ag NWs under a strain rate of ~ 10−2 s−1 and ~ 10−3 s−1, respectively.
