Cube Texture Formation in Ni-8at.%W Alloy Substrates Effected by the Initial Grain Size of Ingot

Abstract

The high critical current density of YBCO-coated conductors prepared by rolling assisted biaxially textured substrate technic is mostly based on the high quality cube-textured substrates. In this paper, the effect of initial grain size of ingot on the microstructure and texture evolutions during cold rolling has been investigated in high alloyed Ni8W ingots, which can affect the cube texture formation in Ni8W alloy substrates subsequently. Finally, high quality cube texture had been obtained in Ni8W alloy substrate with fine initial grain size prepared by advanced SPS technology.
