Abstract

The Mg-added (0%, 5%, and 10%) MgB2/Cu superconducting wires were prepared by the powder-in-tube (PIT) method. Vickers micro-indentation tests were performed on the samples with different peak loads at room temperature. The loading–unloading (P–h) curves were analyzed by the displacement approach to indentation. It was found that hardness (H) and the effective elastic modulus (E) values increased with Mg-added. In addition, these values showed peak load dependence (i.e. indentation size effect (ISE)).
