金属粉末的吸氢统计热力学模型
Statistic Thermodynamic Model of Hydrogen Absorption on Metal Powders
摘要
Abstract
Based on zero-order Bragg-Williams approximation,a new statistic thermodynamic model is presented herein.The distinctive feature of the new model is that an apparent compressibility factor α is introduced to correct the volume change of high-pressure gases and ensure no loop-like curves are obtained in the fitting results.The new model is successfully applied to investigate hydrogen absorption on metal powders.Our results indicate that the model works very well and can be used to predict PCT curves at different temperatures.Hence,our new model exhibits significant potential for application in practical systems.关键词
