摘要
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 relation between the effective hydrogen storage capacity CH of Ti-V-Cr alloys and out-layer electrons,atomic diameter difference,electronegativity difference has been studied.It is shown that their relation can be expressed as TlnCH = 0.45922T＋5044.8（X）2＋1250.6δ2-285.80 n2/3.The factor of out-layer electrons has the largest effect on the CH of Ti-V-Cr alloys,while the factor of electronegativity difference has the smallest effect among the three bond parameters.The effective hydrogen storage capacity of Ti-V-Cr alloys is greater than 2.0wt% when n2/3 values of Ti-V-Cr alloys are between 1.98 and 2.14,2 values are between 0.255 and 0.288 and（X） 2 values are between 0.0638 and 0.0765.
