在100K到350K温度范围内,测量了含氢的Ti,Ti-6Al-4V,Ti-5Al-2.5Sn和Ti-50Nb合金的内耗。发现,除了存在已知的溶于Ti合金的体心立方β相中的氢snoek峰以外,还存在一个新的由溶于其六角密堆α-相中的微量氢所引起的弛豫内耗峰。对产生此峰的机制提出了一个初步的原子模型。Internal friction of hydrogenated Ti, Ti-6A1-4V, Ti-5Al-2.5Sn and Ti-50Nb alloys in the range of 100 K to 350 K was measured. It was found that there was not only a known Snoek peak of hydrogen atoms in the β-phase, but also a new relaxation peak caused by the small amount of hydrogen atoms in the h.c.p. lattice α-phase. The mechanism, by which this new peak is produced, is suggested.
