我们报告的实验结果描述随机多孔Au，这是一种新的材料，专门为这项研究开发的机械故障。利用数字图像分析技术对长度尺度变化超过2个数量级的样品进行了微观结构表征。多孔Au经历了微观结构控制的韧脆转变。在Kahng等人[B 37，7625（1988）]的数值模拟中也发现了类似的转变。
We report experimental results describing the mechanical breakdown of random porous Au which is a new material specifically developed for this study. Digital image analysis was used to characterize the microstructures of the samples which varied by more than 2 orders of magnitude in length scale. The porous Au undergoes a microstructurally controlled ductile-brittle transition. Similar transitions have been found in numerical simulations by Kahng et al. [Phys. Rev. B 37, 7625 (1988)].
