自1974年Reilly等人首先报道FeTi及其氢化物的研究成果以来,已引起有关人士的广泛注意和兴趣.关于FeTiH_z材料内存在的各种物相及其形成机制,至今仍为这一研究领域内正在探讨的问题.值得一提的是Raj等人的工作,他们认为:Fe-H键在FeTi氢化物由β_2相变至γ相起着十分显著的作用。 我们通过不同温度(主要是高于室温)条件下的穆斯堡尔谱的研究,由相应谱的分析结果,得出了与Raj等人的结果显著不同的结论.即Fe-H电磁相互作用,对于形成FeTi氢化物的γ相来说是相当弱的。 Since Reilly et al. First reported the research results of FeTi and its hydride in 1974, it has attracted a great deal of attention and interest from researchers concerned. The various phases existing in FeTiH_z materials and their formation mechanism are still the main research area It is worth mentioning the work of Raj et al., Who argue that the Fe-H bond plays a very significant role in the phase transformation of FeTi hydrides from the β_2 phase to the γ-phase. We study the Mossbauer spectra at different temperatures (mainly above room temperature) and draw conclusions that are significantly different from those of Raj et al., From the analysis of the corresponding spectra, that is, the Fe-H electromagnetic interaction , Which is rather weak for the formation of the γ phase of FeTi hydrides.
