Single-Pass Hot Compression Deformation Behavior and Processing Map ofFe-0.2C-7Mn Medium Mn Steel
摘 要
采用Gleeble-3500型热模拟试验机对Fe-0.2C-7Mn中锰钢进行单道次等温压缩试验,研究了该钢在不同变形温度(950~1 150℃)和应变速率(0.001~1 s-1)下的热变形行为,通过计算应变速率敏感指数、功率耗散效率以及失稳参数建立该钢的热加工图,并获得最佳的热加工工艺窗口。结果表明:随着应变速率的增加和变形温度的降低,该钢的流变应力增大;高变形温度和低应变速率有利于动态再结晶的发生,动态再结晶程度的差异会对应变速率敏感指数产生很大的影响;不同真应变下的失稳区均出现在高温高应变速率区域,并且基本与功率耗散图中的低功率耗散效率区域重合。试验钢的最佳热加工工艺窗口为变形温度975~1 100℃、应变速率0.006~1 s-1。
Abstract
The hot deformation behavior of Fe-0.2C-7Mn medium Mn steel at different deformation temperatures (950-1 150℃) and strain rates (0.001-1 s-1) was investigated by single-pass isothermal compression tests on Gleeble-3500 thermal-mechanical simulator. The processing map of the steel was established by calculating the strain rate sensitivity index, power dissipation efficiency and instability parameters, and the best process window was obtained. The results show that the flow stress of the steel increased with increasing strain rate or decreasing deformation temperature. High deformation temperatures and low strain rates were conducive to the occurrence of dynamic recrystallization. The difference of dynamic recrystallization degree had great influence on strain rate sensitivity index. The instability regions at different true strains appeared in the region of high deformation temperatures and high strain rates, and basically coincided with the low power dissipation efficiency region in the power dissipation map. The best process window for the test steel was deformation temperature of 975-1 100℃ and strain rate of 0.006-1 s-1.
