The effect of rolling parameters such as 35.0%~52.0% reduction rate in recrystallization region
60.2% ~70.3% reduction rate in non-recrystallization region
cooling rate(20~38 ℃/s)on structure and mechanical properties of0.06C-0.31Mo V-Nb-Ti-B microalloying steel has been studied by Cleeble thermal simulation machine.The test results sbowed that with increasing cooling rate
the upper bainite volume percentage increased led to increasing strength of steel
and the more acicular ferrite content in bainite matrix the more upper shelf energy(USE)of steel and the lower ductile brit- tle transition temperature
therefore the acicular ferite in bainite matrix could improve the mechanical propertics of pipeline steel.
