Abstract

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 K-IC at cryogenic temperatures was attempted to estimate with Vickers hardness and crack length. (C) 2001 Elsevier Science B.V. All rights reserved.
