抜粋

Vickers hardness properties of YBCO bulk superconductor have been investigated from 40 to 293 K in this study. Hardness increased up to 18,000 ± 2500 MPa with decreasing temperature. Furthermore, cracks caused by the indentation process were observed with SEM, and the increase in crack length with decreasing of temperature was obtained. Fracture toughness KIC at cryogenic temperatures was attempted to estimate with Vickers hardness and crack length.
