原子尺度的计算机模拟被用来探索双连续纳米多孔金属几何弛豫的主要机制。我们利用一种方法来创建数字样品服从原子模拟，在数量上类似于那些准备实验。这些结构的模拟弛豫，以及模型球形团簇的弛豫，表明表面弛豫效应占主导地位的NP-金属后处理的整体尺寸弛豫。毛细效应在整体松弛中起次要作用。(C)2007由Elsevier Ltd.代表Acta Materialia Inc.出版。
Atomic scale computer simulations are used to probe the dominant mechanisms for the geometric relaxation of bicontinuous nanoporous (np) metals. We utilize a method for creating digital samples amenable to atomic simulations that are quantitatively similar to those prepared experimentally. Simulated relaxations of these structures, as well as the relaxation of model spherical clusters, indicate that the surface relaxation effect dominates the overall dimensional relaxation of np-metals post processing. Capillary effects play a secondary role in the overall relaxation. (C) 2007 Published by Elsevier Ltd. on behalf of Acta Materialia Inc.
