<p>This study examines the effect of temperature and strain rate on microstructure and texture evolution during hot deformation of a Ti-6Al-4Mo-1&#xa0;V-0.1Si alloy. Deformation was conducted in the α, α + β, and β phase fields at strain rates of 0.01&#xa0;s⁻¹, 1&#xa0;s⁻¹, and 10&#xa0;s⁻¹, with samples compressed to 50% height reduction. Peak flow stress decreased with increasing temperature and decreasing strain rate. Significant microstructural and textural changes were observed. At 800&#xa0;°C, α lamellae exhibited kinking and bending with the formation of texture components such as (011̅0)[21̅12̅] and (112̅0)[22̅03]. At 950&#xa0;°C, the microstructure consisted of globular and elongated α, with texture components like (011̅0)[844̅3] and [022̅3] along the compression direction. At 1050&#xa0;°C, martensitic structures formed, accompanied by recrystallized β grains and fibre textures like &lt; 202̅3 &gt; and &lt; 112̅0 &gt; along the compression direction.</p> Graphic Abstract <p></p>
