Solid-state interdiffusion reactions in Ni/Ti and Ni/Zr multilayered thin films

Abstract
We have performed a comparative transmission electron microscopy study of solid‐state interdiffusion reactions in multilayered Ni/Zr and Ni/Ti thin films. The Ni‐Zr reaction product was amorphous while the Ni‐Ti reaction product was a simple intermetallic compound. Because thermodynamic and chemical properties of these two alloy systems are similar, we suggest kinetic origins for this difference in reaction product.
