초록

To improve the texture and the hardness of Ni substrates, we added impurities such as Mn, Fe, Co, Cu and Cr and investigated the effect of impurities on the texture and the hardness of Ni tapes. The Ni tapes with 0.2% Co, Cr, Cu, showed poor in-plane textures. However, the Ni tapes with 0.1 ${\sim}$ O.2% Mn (or Fe), showed much better textures. We'll describe the detailed effects of the amount of Mn impurities.
