Abstract
We evaluated tlie effects of joining processes such as cuntjiet method, shape of joined area find pressure on the electrical and mechanical properties nf lii2223 superconducting tape. Specifically, the current carrying capacity siml bonding strength of the lapjoined tape were measured fis a function of iimaxial pressure and correlated tu (lie microstructurai evolution. It was observed that the current currying capacity was reduced in the transition region of the jointed tape find WHS significantly dependent on the uniaxial pressure. The jointed tiipc, fabricated with n pressure of 1,600 M Pa, showed the highest value of current capacity 90% of the tape itself, It is believed that the highest value of current capacity results from improvements in core density, contacting area and grain alignment. In addition, bonding strength of the jointed tape was evaluated and correlated to the microstritctural évolution.
