摘要：

The mechanism of helically coiled nanofiber formation was described. It was found that the fragment of helically coiled nanofiber with the catalyst particle was formed in a high isostatic pressure (HIP) apparatus. The trnsformation of the spherical particle into an octahedron was performed in the act of nanofiber formation. The results show that the high pressure arising inside the nanofiber lead to the appearance of longitudinal deformation, compression and bending of the fiber.
