根据实验室条件，对原有的高频感应加热设备进行了改造，使之可一次进行１５ｇ左右镍－稀土系列贮氢合金的真空和充氩气熔炼。并以ＬａＮｉ＿５为主要研究对象，通过对加热电压、时间等熔炼工艺及原材料配比进行的研究，表明只有严格控制力。热电压及加热时间，才能获得外观成形良好、内部成分均匀的合金，并确定了真空熔炼及充氦气熔炼的最佳工艺。通过比较当真空度在１０￣（－４）Ｔｏｒｒ以上时，真空熔炼比充氩气熔炼更易获得高质量的合金，进行了吸放氢试验、合金结构分析及相图分析，确定了本研究中所用金属钢在合金配方中的最佳加入量为３３．１％，所熔炼的ＬａＮｉ＿５合金纯度较高、贮氢性能良好。
According to laboratory conditions, the original high-frequency induction heating equipment has been modified so that it can be a nickel-rare earth series about 15g hydrogen and argon gas melting smelting. And LaNi_5 as the main research object, through the heating voltage, time and other smelting process and the ratio of raw materials research shows that only strict control. Thermal voltage and heating time, in order to obtain the appearance of good shape, uniform composition of the alloy, and to determine the vacuum melting and filling the best helium melting process. By comparing the results of vacuum absorption and desorption test, alloy structure analysis and phase diagram analysis, it is found that when the vacuum degree is above 10 ~ (-4) Torr, the vacuum melting is easier to get high quality alloy than argon gas smelting, The optimal addition amount of the metal steel used in the alloy formulation is 33.1%, the purity of the LaNi_5 alloy melted is high, and the hydrogen storage performance is good.
