摘要

在亚稳-β钛合金中，加热到β场进行β再结晶，诱导α相向β相转变。α相的溶解直接影响到β相储能释放过程的进行。利用SEM/EBSD研究了热锻Ti-10V-2Fe-3Al在β场加热和退火过程中β相和α相的行为。实验数据表明，α相对β相边界有很强的钉住作用，控制了β相的恢复和再结晶程度。总的来说，这项研究的结果提供了一个更清晰的材料在这一加工步骤中的行为，并使再结晶β晶粒细化。

Microstructural evolution during beta annealing after hot deformation in the alpha+beta field of metastable-beta Ti-10V-2Fe-3Al alloy

In metastable-β titanium alloys, heating to the β field to carry out β recrystallization induces the transformation of the α phase to the β phase. The dissolving α phase directly affects the progress of the stored energy release processes in the β phase. In this study, the behavior of the β and α phases during heating and annealing in the β field of hot-forged Ti-10V-2Fe-3Al is investigated using SEM/EBSD. The experimental data indicate a strong pinning effect of the β boundaries by α precipitates, controlling the extent of recovery and recrystallization in the β phase. Overall, the results of this investigation provide a clearer view of the material’s behavior during this processing step and enable a refinement of the recrystallized β grains.

期刊介绍： Materialia is a multidisciplinary journal of materials science and engineering that publishes original peer-reviewed research articles. Articles in Materialia advance the understanding of the relationship between processing, structure, property, and function of materials. Materialia publishes full-length research articles, review articles, and letters (short communications). In addition to receiving direct submissions, Materialia also accepts transfers from Acta Materialia, Inc. partner journals. Materialia offers authors the choice to publish on an open access model (with author fee), or on a subscription model (with no author fee).
