摘要

The equipment of RH600 Hydrogen Analyzer (Fusion) was adopted to measure the hydrogen content of Nb47Ti alloy bars, with Φ50 mm×40 mm after different annealing processes in RX-460 electric furnace. Based on the analysis results, a dehydrogenation method was proposed. The results indicate that the main hydrogenation takes place at the annealing temperature of 1200℃, while the hydrogenation can not occur in the subsequent annealing at 950, 930 and 900℃. The hydrogenation phenomenon occurring in Nb47Ti alloy is mainly attributed to the joint effect of the high activity constituent elements and the rare hydrogen atmosphere. The 800℃/3 h and 800℃/6 h vacuum heat treatment can reduce the hydrogen content in Nb47Ti alloy effectively from 60 μg/g to 21 and 29 μg/g, respectively.
