Abstract:

介绍了合金材料吸氢的基本原理及反应机理,主要利用稀土系储氢材料的吸氢模型方程研究了磁性制冷材料La(Fe, Si)_(13)基合金的吸氢特性。通过Chou模型建立了La_(0.7)Pr_(0.3)Fe_(11.5)Si_(1.5)和La_(0.7)Pr_(0.3)Fe_(11.5)Si_(1.5)C_(0.2)合金的吸氢反应分数与时间、温度的具体关系式,探究了2种合金材料的吸氢反应特性。根据模型方程,引入吸氢过程中的重要参数"特征反应时间",得到在等温等压条件下的La_(0.7)Pr_(0.3)Fe_(11.5)Si_(1.5)和La_(0.7)Pr_(0.3)Fe_(11.5)Si_(1.5...
