研究了TiVCr合金的有效储氢量CH与电负性差、原子尺寸参数和外层电子数之间的定量关系,可表示为:TlnCH=0.45922T+5044.8(?X)2+1250.6δ2-285.80n2/3。外层电子数因数对TiVCr合金的CH影响最大,电负性差因数对CH影响最小。当n2/3值在1.98和2.14之间、δ2值在0.255和0.288之间、(?X)2值在0.0638和0.0765之间时,TiVCr合金的有效储氢量大于2.0wt%。
The quantitative relationship between the effective hydrogen storage capacity CH of TiVCr alloy and the electronegativity difference, atomic size parameter and the number of outer electrons was investigated. The quantitative relationship between the number of electrons and the number of outer layers of TiVCr alloy can be expressed as: TlnCH = 0.45922T + 5044.8 (? X) 2 + 1250.6? 2-285.80n2 / 3. The outer electron number factor has the greatest effect on the CH of TiVCr alloy, and the difference coefficient of electronegativity has the least effect on CH. When the value of n2 / 3 is between 1.98 and 2.14, the value of δ2 is between 0.255 and 0.288, and the value of (? X) 2 is between 0.0638 and 0.0765, the effective hydrogen storage capacity of TiVCr alloy is more than 2.0wt%.
