The single pass reduction deformation experiments of a Ti-IF steel (0. 009C
0. 047Ti) at 750 ~ 850 °C with strain rate of deformation 1 -70 s
-1
have been carried out by THERMECMASTOR-Z thermal simulation machine. Based on obtained stress - strain curves with different temperature and strain rate of deformation
it showed that with increasing speed and strain of deformation
the flowing stress increased
while at experimental temperature range the effect of deformation temperature on flowing stress was not obvious. The relation between Zener-Hollomon parameter Z of the Ti-IF steel and strain rate e and temperature T of deformation was Z = ε exp(42 150/T)
