Özet

Prepared by a wet method (BiPb)SrCaCuO superconductors micro-hardness properties was investigated by dynamic micro-indentation technique. The indentation load-displacement curves of the materials were plotted by applied load varying from 200 to 1800 mN. Micro-hardness numbers carry out from loading-unloading process showed load dependence hardness (LIE), i.e., indentation size effect (ISE). The ISE was examined with the theoretical models such as Meyer's law, the Hays-Kendal approach, the Elastic/Plastic Deformation model, the Proportional Specimen Resistance (PSR) model, and the Modified Proportional Specimen Resistance (MPSR) model. MPSR model was obtained the better model to calculate micro-hardness numbers of samples. According to this calculating result, the true hardness of superconductor were increasing with the increasing of the amount of Zn% and.Bi-2212 phase into mixture.
