电沉积可以用来制造新型的杂化纳米晶蜂窝材料，其中纳米晶管的相互连接的网络控制着整体的机械性能。本研究考察了电沉积纳米晶镍增强的传统开孔泡沫铝在单轴压缩过程中的力学性能和失效机制。用复合蜂窝材料方法模拟了中空管状纳米晶泡沫镍的压缩模数和峰值强度的增长，并预测了其行为。(C)2009年Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
Electrodeposition can be used to create new types of hybrid nanocrystalline cellular materials in which the interconnected network of nanocrystalline tubes controls the overall mechanical performance. The present study examines the mechanical performance and failure mechanisms that occur during the uniaxial compression of conventional open-cell Al foams that have been reinforced with electrodeposited nanocrystalline Ni. A composite cellular material approach was used to model the measured increase in compressive modulus and peak strength in terms of the predicted behaviour for a hollow-tube nanocrystalline Ni foam.
