摘要/描述

A single-component, 1104 211:, biaxially textured silver tape was obtained by cold-rolling and annealing. The cold-rolling textures and recrystallization textures of silver were studied systematically. It is shown that a sharp biaxial 1104 texture can be obtained by using higher total rolling reduction, lower reduction per pass and higher annealing temperature. In-plane aligned YBCO film was deposited directly by pulsed laserdeposition PLD. on a textured silver foil having 1104 211: orientation. The critical current density Jc value of 5=105 Arcm2 was obtained at 77 K, 0 T.
