Abstract

Clarifying the bending deformation behaviour of metal foils is essential for meeting the lightweighting requirements of metal honeycomb structures. This study selected Ti65 alloy specimens with various thicknesses and initial α-phase textures to conduct room-temperature three-point bending experiments. A detailed comparative analysis was performed on the bending deformation behaviour of Ti65 alloy sheets and foils. It reveals that in the foil specimens, the weakening effect of surface layer grains is significant. Under the influence of size effects, the springback angle of Ti65 alloy foils with coarse α-phase grains decreases markedly. Additionally, through various methods, including global Schmid factor analysis, lattice rotation analysis, and crystal plasticity finite element method simulations, the specific relationship between α-phase texture and the bending performance of Ti65 alloy foils was thoroughly investigated. The rolling process influences the bending performance of Ti65 alloy by determining the α-phase texture. Unidirectionally rolled Ti65 alloy products exhibit a transverse α-phase texture, which predisposes them to form transverse texture α-phase macrozones during bending. In contrast, cross-directionally rolled Ti65 alloy foils possess a basal α-phase texture biased toward the transverse direction. This not only helps avoid the formation of macrozones but also ensures coordinated deformation across the foil, resulting in superior bending performance.

考虑初始纹理特征和尺寸效应的近α钛合金板材/箔材的弯曲特性和变形微观机制
明确金属箔的弯曲变形行为对于满足金属蜂窝结构的轻量化要求至关重要。本研究选择了具有不同厚度和初始 α 相纹理的 Ti65 合金试样进行室温三点弯曲实验。对 Ti65 合金板材和箔材的弯曲变形行为进行了详细的对比分析。结果表明,在箔片试样中,表层晶粒的削弱效应显著。在尺寸效应的影响下,具有粗α相晶粒的 Ti65 合金箔的回弹角明显减小。此外,通过全局施密德因子分析、晶格旋转分析和晶体塑性有限元法模拟等多种方法,深入研究了 α 相纹理与 Ti65 合金箔弯曲性能的具体关系。轧制工艺通过决定α相纹理来影响 Ti65 合金的弯曲性能。单向轧制的 Ti65 合金产品表现出横向 α 相纹理,这使其在弯曲过程中容易形成横向纹理 α 相大区。相反,横向轧制的 Ti65 合金箔具有偏向横向的基底 α 相纹理。这不仅有助于避免大区的形成,还能确保整个箔片的协调变形,从而实现优异的弯曲性能。
