چکیده انگلیسی
The effects of cold pre-deformation on aging behavior and mechanical properties in Ti-1300 alloy are examined using optical microscopy, scanning electron microscopy, and transmission electron microscopy analyses. Results show that cold pre-deformation markedly influences the aging behavior and mechanical properties of Ti-1300 alloys. The cold deformation mechanism of Ti-1300 alloys is found to involve the dislocation slip and twinning. The microstructures of the pre-deformation specimens, which were aged at 550 °C, comprise α phases in β matrices regardless of cold deformation reduction. Fine/uniform and coarse/needle-like α precipitates are formed in the slightly and heavily deformed zones, respectively. The Vickers hardness of Ti-1300 alloys aged after cold pre-deformation respectively decreases and increases with increased aging temperature and cold pre-deformation reduction.
