Mixtures of pure elemental Ag and Cu powders or, thin foils of the pure metals alternately stacked up to more than one hundred layrs, have been subjected to the repeated compressive plastic deformation by the use of a hydraulic press. After each compressive deformation, which reduces the sample thickness to about 1/2, sample was cut into two pieces and one piece was stacked on another to be pressed again. Formation of nano-meter sized crystal grains and super-saturated solid solutions were confirmed. Fine layrs of less than 100 nano-meters were formed by the repeated pressing of 20 times.

纯元素Ag和Cu粉末的混合物或纯金属的薄箔交替堆叠多达100层以上，已经通过使用液压机经受重复压缩塑性变形。在每次压缩变形（其将样品厚度减小至约1/2）之后，将样品切成两片，并且将一片堆叠在另一片上以再次压制。证实了纳米晶粒和过饱和固溶体的形成。通过重复压制20次形成小于100纳米的精细层。
