Abstract:The flow stress behavior of TA15 titanium alloy during hot compression was studied on a Gleeble−3800 thermal/mechanical simulator, and the hot continuous rolling process of TA15 small bars was designed at 850−950 ℃ based on the experimental results. The results show that the microstructure and mechanical properties of TA15 small bars could meet the requirement of the specification after proper continuous hot rolling process.
Key words: titanium alloy; hot continuous rolling; microstructure; mechanical properties
