氢能源是一种理想的二次能源。随着氢能的开发和利用,贮氢材料的研究日益受到重视。Ti-Mn合金是较有希望的贮氢材料之一。Gamo等人对Ti-Mn系Laves相的贮氢性能进行了系统的研究。他们认为,Ti-Mn二元合金中最宜作为贮氢材料的组成为TiMn_(1.5)。但在文献[2,3]所报道的Ti-Mn二元合金相图中,TiMn_(1.5)分别处于Cl_4型结构Laves相均匀区中间或P+C14两相区,这就难以从相关系的角度解释TiMn_(1.5)作为贮氢材料最佳组成的原因。为此,我们对Ti-Mn二元系Laves相的均匀区重新进行了测定。
Hydrogen energy is an ideal secondary energy. With the development and utilization of hydrogen energy, the research of hydrogen storage materials is paid more and more attention. Ti-Mn alloy is one of the more promising hydrogen storage materials. Gamo and others on the Ti-Mn Laves phase of the hydrogen storage properties of a systematic study. In their opinion, TiMn_ (1.5) is most suitable as the hydrogen storage material in Ti-Mn binary alloys. However, in the phase diagram of Ti-Mn binary alloy reported in [2, 3], TiMn_ (1.5) is in the middle of Laves phase or in P + C14 phase of Cl_4 structure respectively, Explain the reason why TiMn_ (1.5) is the best composition of hydrogen storage material. To this end, we re-measured the homogeneity of the Ti-Mn binary Laves phase.
