title: [Determination of hydrogen in 2,091 Al-Li alloy].
abstract: High volatility element Li exists in 2091 Al-Li alloy, and makes the difficulty for the determination of hydrogen. A lot of tests were done, for example, how to distinguish the body and surface hydrogen, to choice heating power, heating time and the size of sample. Then the analytical method is established and many discussions were done. The reproducibility and accuracy is satisfactory, and compared with the Russian Al-Li alloy hydrogen standard sample.
