Abstract—Scanning electron microscopy, electron microprobe and X-ray diffraction analyses, and durometry are used to study changes in the structure, phase composition, and hardness of a quenched titanium Ti‒10V–2Fe–3Al alloy in the course of aging at 500°С for 2–32 h. A complex analysis of changes in the lattice parameters of the primary and secondary α phases formed in the alloy during aging has been performed for the first time using full-profile X-ray diffraction analysis. Aging-induced changes in the hardness of the alloy are shown to be determined both by the sizes of formed secondary α-phase particles and changes in the alloying of the matrix β solid solution.

钛Ti–10V–2Fe–3Al合金时效过程中相结构和参数的转变及其与强化的关系

摘要—使用扫描电子显微镜,电子显微探针和X射线衍射分析以及硬度计来研究淬火的Ti‒10V-2Fe-3Al钛合金在500时效时的组织,相组成和硬度的变化。 °С2–32小时。首次使用全轮廓X射线衍射分析法对合金在时效过程中形成的初级和次级α相的晶格参数变化进行了复杂的分析。合金引起的时效变化是由形成的二次α相颗粒的尺寸和基体β固溶体合金化的变化决定的。
