Abstract:IMI834, as a high-performance titanium alloy resistant to 600 ℃, faces limitations in its application due to issues such as a narrow processing window, weak deformation ability, and high deformation resistance. Although it is feasible to control the sheet's microstructure and texture by adjusting the rolling thickness and post-rolling heat treatment, related research remains insufficient. In this study, the effects of deformation and solution treatment temperature on the microstructure and texture of IMI834 sheets was investigated by scanning electron microscopy and back scattered electron diffraction techniques. The results indicate that as the rolling deformation increases, the sheet's microstructure gradually transforms into banded and equiaxed fine-grained structures, in which the banded structure exhibits 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.
