A new tensile test method was developed and was applied to a single crystalline gold nanowire with a square section of 189 nm. The nanowire, which was mounted on a lozenge-shaped silicon frame, was pulled by a compressive load on the top face of the frame. Although the applied load increased monotonically in the early stages of deformation, it dropped rapidly at a certain displacement. In-situ TEM observation indicated that the rapid decrease was due to crystallographic slip generation. The critical resolved shear stress at yielding was evaluated to be 325.8 MPa, which was about 600 times larger than that of bulk.

提出了一种新的拉伸测试方法，并将其应用于截面为189 nm的单晶金纳米线。纳米线安装在菱形硅框架上，通过框架顶面上的压缩载荷来拉动。虽然施加的载荷在变形的早期阶段单调增加，但在一定的位移，它迅速下降。原位TEM观察表明，快速下降是由于晶体滑移的产生。屈服时的临界分解剪切应力被评估为325.8 MPa，这是大约600倍大于本体。
