Abstract

Nanocrystalline Ni-Fe alloy foils were fabricated by using a continuous electrodeposition system, and then they were annealed at different temperatures ranging from room temperature to 650 ℃. A ductile-brittle-ductile evolution of these alloy foils was observed along with the increase of annealing temperature, and was affected by iron content. The first and second transformation took place at below 300 ℃ and over 500 ℃, respectively. Iron improved thermal stability of nanocrystalline Ni-Fe alloys. The XRD data indicated that for Ni100-xFex (x > 55) alloys bcc to fcc phase transformed at 300 ℃ and completely at 500℃.
