Progression of Late Stage Abnormal Grain Growth of Electroformed Nanocrystalline Ni Without the Addition of Grain Refiner

A thin amorphous interfacial phase within microstructure is one of the promising strategies for designing better nanostructured materials. Nickel and Ni–Al nanocomposites fabricated by pulsed electrodeposition are deformed in tension and selected samples are heated to elevated temperatures. Here, the authors report that a well‐dispersed Al nanoparticle, possessing a thin layer of amorphous oxide shell, reinforcement in nanocrystalline Ni matrix enhances tensile strength by ≈60% without losing ductility and also provides better microstructural stability due to existence of local microstructural gradient.
