In this paper, we have investigated the size and shape effects on creep and diffusion phenomena at the nanoscale. From a classical thermodynamic model, the higher diffusion of nanostructures is explained. As creep is particularly due to diffusion processes, it is therefore important to consider it at the nanoscale. Therefore, to be able to control creep in the nanoworld, temperature and stress thresholds, taking into account the size and shape of the nanostructure, are defined.
在本文中，我们研究了纳米尺度下尺寸和形状对蠕变及扩散现象的影响。基于经典热力学模型，解释了纳米结构具有较高扩散率的原因。由于蠕变尤其归因于扩散过程，因此在纳米尺度上考虑蠕变非常重要。所以，为了能够在纳米世界中控制蠕变，定义了考虑纳米结构尺寸和形状的温度及应力阈值。
