FeTi1.3（Mn）y合金的贮氢性能及其吸放氢机理研究
, PP. 805-808
Keywords: 贮氢合金,贮氢性能,活化性能,吸放氢机理
Abstract:
系统研究了ＦｅＴｉ１．３（Ｍｎ）ｙ（ｙ＝０,０．０１３,０．０２６,０．０２９,０．０５２）合金的贮氢性能.研究结果表明,在ＦｅＴｉ１．３合金中添加少量的富Ｃｅ混合稀土Ｍｍ可以显著改善合金铁活化性能,使未经任何活化处理的合金在室温下经较短孕育的期就能吸放氢.这主要是因为,在合金中分别以β－Ｔｉ和颗粒夹杂形式存在的过量的Ｔｉ和少量的Ｍｎ在氢化过程中首先与氢反应,伴随着的晶格膨胀导致合金中出现大量的显微裂纹,从而使合金的活化性能明显改善.
