运用RH 4 0 2测氢仪测定具有高挥发性物质锂的铝 锂合金的固态氢含量具有相当难度 ,本文就如何鉴别体内氢和表面氢、如何选择加热功率和加热时间及试样大小做了大量探索实验 ,初步形成了可行的铝 锂固态氢含量的分析方法。同时就测量的误差来源及测氢过程中应注意之点进行了讨论。结果重复性好 ,且结果比较准确 (利用俄罗斯铝 锂合金氢标样比较 )。 It is quite difficult to determine the solid state hydrogen content of Al-Li alloy with high volatility lithium using RH402 hydrogen analyzer. How to choose the heating power and heating time and the sample size A large number of exploration experiments, initially formed a viable Al-Li solid-state hydrogen content analysis. At the same time, the sources of error and the points that should be paid attention to during hydrogen measurement are discussed. The result is good repeatability, and the result is more accurate (compare with the Russian Al-Li alloy hydrogen standard sample).
