The hydrogen absorption properties of low activation material, Ti-6A1-4V alloy, were studied by using thermal desorption spectroscopy. The polished sample was exposed to the hydrogen atmosphere with pressure from 0.03 to 100 Pa, temperature from 500-820 K and time duration from 1 to 48 hrs. The absorption amount of the polished sample was very low, much below the critical concentration (1000ppm) for the hydrogen embrittlement to take place. However, the absorption amount of pre-heated sample was observed to be large. The highest concentration was about 250ppm under the temperature of 650 K when the pressure was kept 0.3Pa. Thus value is still lower than the critical conentration.The interpretation for hydrogen absorption behavior was much deepened by the present experiment. It is also seen that Ti-6A1-4V alloy can be used for the structure material of a fusion reactor.

利用热脱附谱研究了低活化材料Ti-6Al-4V合金的吸氢性能。将抛光的样品暴露于压力为0.03 - 100 Pa、温度为500-820 K、持续时间为1 - 48 h的氢气气氛中。抛光样品的吸收量很低，远低于发生氢脆的临界浓度（1000 ppm）。然而，观察到预热样品的吸收量较大。当温度为650 K，压力为0.3Pa时，浓度最高可达250 ppm。本实验进一步加深了对吸氢行为的解释。Ti-6Al-4V合金可作为聚变堆的结构材料。
