| Abstract | The microstructure/texture evolution (MTE, for short) map and processing map of a new near a titanium alloy Ti65 were constructed in order to investigate the workability and microstructure evolution of hot deformation. The processing map illustrated four domains, two summit domains and two instability domains. The morphologies of the a phase changed from the spheroidization (alpha +beta region) to the deformed and elongated beta grains (near the beta transus temperature T-beta), and then to the obvious dynamic recrystallization (DRX) (beta region) with the temperature rising from 930 degrees C to 1140 degrees C. Deformation in the alpha + beta field mainly generated the texture component with [0001] or [02 (2) over bar3] parallel to radial directions (RDs). While deformation in the beta phase field formed two types of texture component with [0001] parallel to RDs and [2 (1) over bar(1) over bar0] parallel to compression direction. An optimized processing map was summarized by overlaying the macro-instability map on the original processing map, and the instability domain of Ti65 alloy was confirmed in the area with the strain rate higher than 0.01 s(-1). |
