The use of highTcsuperconductors, namely YBa2Cu3O7−x, in the design of electrical componentry shows a great potential for energy savings in the transmission and generation of electrical power. Through characterization of the physical and mechanical properties of these materials, their usefulness in engineering practices can be predicted. The strain reqiured to form and propagate cracks has been considered. The role of crystallographic texture in achieving optimum mechanical and electrical properties will also be discussed.
