摘要
基于Fick第二定律,推导出了一种新的氢渗透数学模型,并成功编制了相应的Matlab计算程序。根据该模型,建立了一种计算Nb基渗氢合金氢扩散系数和溶解系数的新方法;通过对Nb基合金在不同温度下的实例计算,并与实验和文献结果相比较,证实了本模型的可行性和有效性。
Based on Fick’s second law,a new mathematical model of hydrogen permeation was derived,and the corresponding Matlab program was compiled successfully.According to this model,a new method for calculating hydrogen diffusion coefficient and solubility coefficient of Nb-based hydrogen permeable alloy was established.Based on the calculated results of Nb-based hydrogen permeable alloy at different temperatures and the comparison with experimental and literature results,the feasibility and effectiveness of the proposed model were verified.
