摘要
用穆斯堡尔效应及 X 射线衍射研究了 Ti_(0.15)(Cu_(1-x)Fe_x)及其氢化物结构,证实当 x>0.2,合金材料结构发生了相变,即由 TiCu 单一结构变成含有 TiFe 结构的混合体.实验结果表明,由于铁的加入改善了储氢材料 TiCu 的激活性能,且相应的氢化物 Ti_(0.15)(Cu_(1-x)Fe_x)Hy 具有明显的顺磁性,对上述结果作了一定解释.
The structure of Ti_(0.51) (Cu_(1-x)Fe_x) and its hydrides is investigated using M_ssbauer effect and X-ray diffraction.It is confirmed that the crystalline structure of alloys undergo phase transition for x>0.2,namely,the structure will form the mixture of like γ-TiCu and like TiFe from single like γ-TiCu. The activition property of TiCu,as hydrogen storage materials is improved by adding Fe into the alloy.Ti_(0.51)(Cu_(1-x)Fe_x)hydrides possess strong parama- gnetism.Some explanations are given.
