  • Patent number: 10801933
    Abstract: The present invention provides a self-healing method for fractured SiC amorphous nanowires. A goat hair in a Chinese brush pen of goat hair moves and transfers single crystal nanowires under an optical microscope. On an in-situ nanomechanical test system of a TEM, local single crystal nanowires are irradiated with an electron beam for conducting amorphization transformation. Amorphous length of a single crystal after transformation is 60-100 nm. A fracture strength test is conducted on the amorphous nanowires in the single crystal after transformation in the TEM; and fracture strength of the amorphous nanowires is 9-11 GPa. After the amorphous nanowires are fractured, unloading causes a slight contact between the fractured end surfaces; and self-healing of the nanowires is conducted after waiting for 16-25 min in a vacuum chamber of the TEM. Atom diffusion is found at a healed fracture through in-situ TEM representation; and recrystallization is found in the amorphous nanowires.

    Abstract: A self-healing method for fractured SiC single crystal nanowires. A hair in a Chinese brush pen of yellow weasel's hair moves and transfers nanowires, which are placed on an in-situ TEM mechanical microtest apparatus. An in-situ nanomechanical tension test is realized. The nanowires are loaded. Displacement is 0-200 nm. Fracture strength of the single crystal nanowires is 12-15 GPa. After the nanowires are fractured, unloading causes slight contact between the fractured end surfaces, electron beam is shut off, and self-healing of the nanowires is conducted in a vacuum chamber. Partial recrystallization is found at a fracture after self-healing through in-situ TEM representation. A fracture strength test is conducted again after self-healing. A fractured position after healing is the same as the position before healing. The fracture strength of the single crystal nanowires after self-healing is 1-2.5 GPa. The recovery ratio of the fracture strength is 10-20%.
