摘要：

Deformation characteristics of beta titanium alloy Ti-15V-3Cr-3Sn-3Al at elevated temperature were examined. Analysis by constitutive equation shows the deformation can be controlled by a single activated rate process, and activation energy for deformation is (253 +/- 10) kJ.mol-1, which is close to the value of self diffusion of titanium in Ti-V binary alloys. The grain refinement due to recrystallization occurred above 1 373 K and partial recrystallization did between 1 273 and 1 373 K. While, recrystallization did not occur and grain boundary fracture was resulted below 1 173 K.
