Abstract

We calculated the compaction parameters of CoSb₃ thermoelectric powders under field-activated sintering. The values of the creep activation energy, sensitivity to the strain rate, and the complex parameter of the material characterizing the state are obtained. The compaction of the powders is due to the mechanisms of grain sliding in the sample. We performed the computer simulation of the sintering process by the finite element method. The change in the dimensions of the sample is calculated using the creep deformation model. The simulation results correspond to the experimental data.

烧结激活下CoSb 3方钴矿纳米粉体的压实机理研究

摘要

我们计算了现场活化烧结下CoSb ₃热电粉末的压实参数。获得蠕变活化能，对应变速率的敏感性以及表征状态的材料的复杂参数的值。粉末的压实是由于样品中颗粒滑动的机理。我们通过有限元方法对烧结过程进行了计算机模拟。使用蠕变变形模型计算样品尺寸的变化。仿真结果与实验数据相对应。
