为了克服Li、Al之间熔点差别大的缺点,采用分段式铸造法来大量生产具有储氢潜力的LiAl合金。使用X射线衍射和电感耦合等离子体原子发射光谱法,光学显微镜分析了铸造LiAl合金的组织。结果表明,分段式铸造法可以成功地制备出单相LiAl合金。TPD和X射线衍射分析表明,球磨LiAl合金在6.5 MPa、400℃氢化12 h可获得最高的储氢能力2.4%。
In order to overcome the disadvantage of large difference in melting point between Li and Al, a segmented casting method is used to mass produce LiAl alloy with hydrogen storage potential. The microstructure of the cast LiAl alloy was analyzed by X-ray diffraction and inductively coupled plasma atomic emission spectrometry. The results show that the segmented casting method can successfully prepare single-phase LiAl alloy. TPD and X-ray diffraction analysis showed that the maximum hydrogen storage capacity of 2.4% can be obtained by ball milling LiAl alloy at 6.5 MPa and 400 ℃ for 12 h.
