高强钢300M静态再结晶动力学研究
Static recrystallization behavior of the high strength steel 300M
摘要
Abstract
To research the static recrystallization behavior of high strength steel 300M,single/double-pass hot compression tests of 300M steel were carried out using Gleeble-3800 thermal simulation experiment equipment.The effects of deformation temperature,strain rate,height reduction and initial grain size on the volume fraction of static recrystallization were analyzed by double-pass hot compression tests.It is found that the volume fraction of static recrystallization rapidly increases with increasing deformation temperature,strain rate or height reduction,while it decreases with increasing initial grain size.Initial grain size has less effect than the others.A static recrystallization volume fraction model and a completely static recrystallization grain size model of 300M steel were established based on the results of double-pass and single-pass hot compression tests,respectively,and the static recrystallization volume fraction model was verified to be correct by single-pass hot compression tests.关键词
