中文摘要

The flow stress behavior of commercial pure titanium (CP-Ti) sheet was studied by uniaxial warn tension tests at temperatures ranging from 623 K to 773 K and strain rates from 5.0 × 10?2 to 8.3 × 10?4 s?1. A mathematical model using an updated Fields–Backofen (FB) equation was established to describe the flow stress behavior of CP-Ti during warm tensile testing. The results show that the flow stress of CP-Ti is evidently affected by both deformation temperature and strain rate, i.e., the flow stress decreases with the decrease of strain rate and the increase of deformation temperature, and a typical characteristic of dynamic recrystallization softening.

The flow stress curves analyzed by FB equation shows good agreement with experimental flow curves for different temperatures and strain rates for CP-Ti sheet.
