The single pass thermal compression test of 0.019C and 0.052C two kinds of ultra-low carbon bainite (ULCB)steel with deformation 5%~50%
strain rate 2s
-1
at 1100 ℃ has been carried out by Thermechmastor-Z thermal simulation machine.Results showed that as deformation was lower than 40% the deformation-recrystallization behavior of two kinds of ULCB steel was same that was to form crystal nucleus of recrystallization with 10% deformation
partially recrystallize with 20% deformation
and basically perform recrystallization with 40% deformation. With deformation more than 40%
the grain size of 0.052C ULCB steel was more fine and uniform than that of 0.019C ULCB steel.
