The Mechanical Properties of Y-Doped Bi-2223 Superconductors

In this study the mechanical properties of Bi_1.7?x Y _x Pb_0.3Sr₂Ca₂Cu₃O _y (x=0, 0.05, 0.1, and 0.25) samples with doped Yttrium are investigated. The load-independent Vickers hardness (H ₀), Young’s modulus, and yield strength of samples are calculated. The possible reasons for the observed changes in mechanical properties are investigated by using different approaches such as the Hays–Kendall approach. These mechanical properties of the samples were found to be load and Yttrium content dependent.
