采用真空镀膜和溅射法等结晶成长技术制成的两种以上金属纳米尺寸多层复合材料,具有优良的力学、电学和磁性能。但是采用这类结晶成长技术制作超薄多层复合材料,在技术上和经济上颇多困难。因此,确立了用两种金属薄板交互重叠后通过反复热轧和冷轧制造纳米尺寸层厚的多层?.. Two or more metal nano-scale multi-layer composites made of crystal growth technology such as vacuum coating and sputtering are excellent mechanical, electrical and magnetic properties. However, it is technically and economically difficult to fabricate ultrathin multilayer composites using such crystal growth techniques. Therefore, it has been established that a multilayer of nanometer-sized layer thickness can be produced by repeated hot-rolling and cold-rolling after alternately overlapping two kinds of metal sheets.
