Abstract系统研究了非化学计量比合金La0.6Nd0.4Ni4.8Mn0.2M0.1(M=Cu,Zr)的贮氢性能。结果表明,添加Cu能提高合金的平台压力,减轻滞后效应;而添加Zr能够有效提高合金的动力学性能和抗粉化性能,降低平台压力。但Cu和Zr的添加使贮氢容量有所降低。研究表明,XRD(111)主峰半高宽FWHM值及晶格常数a/c值与合金的滞后因子有相同的变化趋势,平台压力、吸氢焓变与晶胞参数α有很好的线性关系。
Other AbstractHydrogen storage properties of the nonstoichiometric alloys of La0.6Nd0.4Ni4.8Mn0.2M0.1(M=Cu,Zr) have been systematically investigated. Experimental results showed that Cu addition increased the plateau pressure and alleviated the hysteresis while Zr addition effectively improved the absorption kinetics, enhanced the pulverization resistant capability and lowered the plateau pressure. However, additions of Cu and Zr addition impaired the hydrogen storage capacity of the alloys. It was found that the hysteresis factors was correlated with FWHM of (111) peak and α/c value of the alloys, and both the plateau pressure and enthalpy had good linear relations With the lattice parameter α.
