摘要 采用金相(OM)、电子背散射衍射(EBSD)、透射电子显微镜(TEM)等手段研究了Ti-8Al-1Mo-1V钛合金片层组织在热轧及轧后退火过程中的组织演变规律及机制。研究结果表明:热轧及轧后退火难以实现片层α相的球化,仅能实现α相的连续化分布及β相的球化。热轧过程中位错密度无法有效累积是造成片层α相再结晶驱动力缺失的主要原因。同较粗的片状α相相比,在相同轧制力下,细小β相更易破断,并在随后的退火过程中实现扩散球化。根据分析,本工作提出了Ti-8Al-1Mo-1V钛合金片层组织热轧+退火过程中的组织演变机制。此外研究发现,Ti811钛合金片层组织在热轧过程中可形成织构指数为(0221)[3122]的板织构。

Abstract: The lamellar microstructure's evolution pattern and mechanism for Ti-8Al-1Mo-1V titanium alloy during hot rolling and subsequent annealing were studied by means of OM, EBSD, TEM etc. The results show that: hot rolling and subsequent annealing can not easily realize the glo-bularization of lamellar α phase. These processes can only realize the continuous distribution of α phase as well as the globularization of β phase. Insufficient accumulation of dislocation density during hot rolling is the main reason causing the lack of driving force for recrystallization for lamellar α. By comparing with the thick lamellar α phase, the thin and tiny β phase can be more easily broken into segments under the same rolling force. In the following annealing process, the segmented β phase can realize globularization through diffusion. Based on analyses, this work proposes the lamellar microstructure's evolution mechanism for Ti-8Al-1Mo-1V titanium alloy. In addition, it is found that the (0221)[3122] planar texture can be formed during the hot rolling of Ti-8Al-1Mo-1V titanium alloy with lamellar microstructure.
