通过文献调研,总结了氢在不同金属熔体中溶解度变化规律。通过比较不同影响因素的作用,指出氢与金属熔体的电子相互作用是决定氢在金属熔体中溶解度的主要因素。基于近自由电子模型,提出了表征这种电子相互作用和计算氢在金属熔体中溶解度的金属熔体有效电荷密度模型。结果表明:氢在过渡族金属熔体中的溶解度远高于在其他金属熔体中的溶解度,而且随着原子序数的变化呈现有规律的变化,金属熔体有效电荷密度模型很好地解释了这种变化规律。
Through the literature research, summarizes the hydrogen solubility in different metal melt changes. By comparing the effects of different influencing factors, it is pointed out that the electronic interaction between hydrogen and metal melt is the main factor that determines the solubility of hydrogen in the metal melt. Based on the near free electron model, an effective charge density model of metal melt is proposed to characterize this kind of electronic interaction and to calculate the solubility of hydrogen in the metal melt. The results show that the solubility of hydrogen in the transition metal melt is much higher than that in other metal melts and changes regularly with the atomic number. The effective charge density model of the molten metal is well explained The law of change.
