Development of Cube Texture in a Silver-Nickel Bi-layer Sheet

An Ag/Ni bi-layer sheet was fabricated by the combination of powder metallurgy, diffusion bonding, cold rolling and texture annealing processes. After heat treating the cold rolled thin Ag/Ni bi-layer sheet at $900^{\circ}C$ for 4h, the excellent cube texture was developed on nickel surface. Qualitative chemical analysis using EPMA showed that inter diffusions of Ni and Ag in Ag/Ni bi-layer composite were negligible. It showed that Ag can be used as a chemical barrier for Ni and vice versa.
