| 摘 要： | 文章采用Gleeble-2000热模拟试验机对1Cr20Co6Ni2WMoV热强钢的热变形行为进行研究。变形温度为950℃,1000℃,1050℃,1100℃,1160℃,变形速率为0．01s~(-1),0．1s~(-1),1s~(-1),10s~(-1)。结果表明．1Cr20Co6Ni2WMoV钢在低应变速率热压缩变形过程中发生明显的动态再结晶;当应变速率大于10s~(-1)时,只发生动态回复。动态再结晶晶粒随变形温度降低,应变速率升高而减小。随应变速率的提高,峰值应力和峰值应变均升高。 |

| Abstract: | The hot compression behavior of 1Cr20Co6Ni2WMoV heat-resisting steel is investigated over a range of temperature (950℃to 1160℃)and strain rate(0.01s~(-1) to 10s~(-1)),by isothemal compression of Gleeble-2000 machine.The results show that dynamic recrystallization occurs abovely during the samples are compressed at low strain rate.Dynamic recovery occurs when the strain rate over 10s~(-1).The size of dynamic recrystallization grains decreases with reducing of deformation temperature and rising of strain rate. |
| Keywords: | 1Cr20Co6Ni2WMoV heat-resisting steel hot compression flow stress activation energy |
