摘要利用小角X射线和中子散射对Ti-7 Mo中的纳米级析出相进行了非定域定量分析。和Gum金属，一种Ti-Nb基合金。成核和粗化动力学在Ti-Nb合金中比在Ti-Mo合金中更快，大概是因为Nb在Ti中比Mo扩散得更快。因此，Mo基-Ti合金在时效期间比Nb基-Ti合金更稳定。据作者所知，这是第一个出版物量化的大小，体积分数和元素分配的胶金属。
Abstract Small angle X-ray and neutron scattering provide a non-localised quantitative analysis of nanoscale precipitates in Ti-7Mo at.% and Gum metal, a Ti-Nb based alloy. The nucleation and coarsening kinetics are more rapid in the Ti-Nb alloy than the Ti-Mo alloy, presumably as Nb diffuses more rapidly than Mo in Ti. Therefore Mo-based -Ti alloys are more stable during ageing than Nb-based -Ti alloys. To the authors’ knowledge, this represents the first publication quantifying size, volume fraction and element partitioning in Gum metal.
