我们研制的氢原子频标,其氢源系统原来使用钢瓶,它既笨重,又不安全,使用也很不方便。为了使氢原子频标小型化,我们采用冶金部有色金属研究院研制成功的一种镧镍合金材料制成氢储存器,以代替钢瓶,体积缩减到只有原来的1％,且具有氢气纯度高、安装简便、使用安全、造价低、寿命长等优点。镧、镍经清洁处理后,按La+5Ni配比,换算成重量百分比为La=32.12％,Ni=67.88％,放入ZG-25型中频感应炉冶炼。经退火、淬火处理,所得镧镍合金在浇铸温度较低时呈细粒
We developed the hydrogen atomic frequency standard, the hydrogen source system originally used cylinders, it is bulky, but also not safe to use is also very inconvenient. In order to miniaturize the hydrogen atomic frequency standard, we use a lanthanum-nickel alloy material successfully made by the Ministry of Metallurgy Nonferrous Metal Research Institute to make a hydrogen storage instead of a cylinder, the volume is reduced to only the original 1%, and the hydrogen purity is high , Easy to install, safe to use, low cost, long life and other advantages. After the lanthanum and nickel are cleaned, the La + 5Ni mixture is converted to the weight percentage of La = 32.12% and Ni = 67.88%, and put into a ZG-25 medium-frequency induction furnace for smelting. After annealing, quenching, the resulting lanthanum-nickel alloy was fine when the casting temperature is low
