用球形金刚石针尖（直径约10 μm）对高取向热解石墨（0001）表面进行了600 °C的纳米压痕实验。通过暗场扫描透射电子显微镜对压痕的横截面观察显示，在高温下，通过弯曲形成扭结的石墨晶体的非弹性变形的趋势增加。
Nano-indentation at temperatures up to 600 °C has been applied to the (0001) surface of highly oriented pyrolytic graphite using a spherical diamond tip (∼10 μm diameter). Cross-sectional observations of the indentations by dark field scanning transmission electron microscopy show an increased tendency at high temperature for inelastic deformation by buckling of the graphite crystals with kink formation.
