Hardness measurements identified that the relationship between the yield strength ( one-third of hardness) which increased with decrease of layer thickness for Cu/ Ni multilayers and single layer thickness at sub-micron length scale& could be described by the Hall-Petch ( H-P) formula for dislocation pile-up.

结果表明，当膜厚在亚微米范围内时，Cu/Ni多层膜的屈服强度（为硬度值的1/3）与单层膜厚之间符合基于位错塞积模型的Hall-Petch（H-P）关系式；
