Abstract
Microhardness studies are carried out on the (001) plane of faceted crystals of the Bi2Sr2CuO6 (2201) and Bi2Sr2CaCu2O8 (2212) phases with the help of a Knoop indenter. Peculiarities in the effect produced on the microhardness by the indenter orientation relative to crystal faces, the presence of lead in the structure, and the force applied to the indenter (scale effect) are detected. It is found that crystals of the 2212 phase exhibit the strongest dependence of the microhardness on the above factors.
