IMI834, as a high-performance titanium alloy resistant to 600℃ high temperatures, faces limitations in its application due to issues such as a narrow processing window, weak deformation ability, and high deformation resistance. Although controlling the sheet"s microstructure and texture by adjusting the rolling thickness and post-rolling heat treatment is feasible, related research remains insufficient. In this study, scanning electron microscopy and backscattered electron diffraction techniques were employed to investigate the effects of deformation and solution treatment temperature on the microstructure and texture of IMI834 sheets. The results indicate that as the rolling deformation increases, the sheet"s microstructure gradually transforms into banded and equiaxed fine-grained structures, with the banded structure exhibiting an RD texture. Additionally, reversing the rolling direction can increase the proportion of equiaxed fine-grained structures. Appropriate solution treatment can effectively weaken the basal texture, thereby reducing the sheet"s deformation anisotropy. This study provides both theoretical and practical foundations for controlling the texture and improving the performance anisotropy of near-α high-temperature titanium alloy sheets.
