Summary

Researchers grew hexagonal single crystals of the carbon molecule C70 and studied their mechanical properties at low temperatures for the first time. Microhardness measurements revealed anisotropic microplastic behavior and temperature-dependent deformation characteristics in this fullerene material.

Hexagonal single crystals of C70 down to 1–2 mm in size were grown, which allowed the investigation of their low-temperature mechanical properties for the first time. Morphology, microplasticity anisotropy, and the temperature dependence of Vickers microhardness HV (T) of the C70 crystals involving all known phase transitions were studied with the aid of optical microscopy and microindentation in the temperature range 77–350 K. The association of the features of HV (T) dependence with orientation phase transformations was analyzed. It is suggested that microplasticity anisotropy of the C70 crystals correlates with the active slip systems.
