摘要： Nanostructured materials that contain amorphous intergranular films (AIFs) are described herein. Amorphous intergranular films are structurally disordered (lacking the ordered pattern of a crystal) films that are up to a few nanometers thick. Nanostructured materials containing these films exhibit increased ductility, strength, and thermal stability simultaneously. A nanocrystalline material system that has two or more elements can be designed to contain AIFs at the grain boundaries, provided that the dopants segregate to the interface and certain materials science design rules are followed. An example of AIFs in a nanostructured Cu—Zr alloy is provided to illustrate the benefits of integrating AIFs into nanostructured materials.
