After studying the preparatory subject areas about the mechanical properties of materials and the superconductivity, in our original research, we have investigated the change in hardness of the superconducting BiPbSrCaCuO bulk material with addition of different molar percentages of Zn, using Vickers Hardness test. In our research, we have found that addition of Zn in small percentages like 3, 5 and 8% the HV values do not change significantly, but as the Zn percentage range increases from 10% up to 50% the value of HV values also increases.

Maddenin mekanik özellikleri ve süperiletkenlik üzerine yapylan ön çaly?madan sonra, BiPbSrCaCuO süperiletkenin sertlik ölçümü Vickers setlik testi kullanylarak yapylmy?tyr. HV de?erlerinin %3, 5 ve 8 gibi %Zn ilavesiyle ciddi bir ?ekilde etkilenmedi?i, ilave oranynyn %10'dan %50'yekadar artmasyyla birlikte olan Zn ilavelerinde ise HV de?erinin artty?y bulunmu?tur.
