文章亮点

(1) 构建了两种中锰钢的本构方程和热加工图

(2) 比较了固溶铌和碳化铌析出对动态再结晶的抑制效果

(3) 系统地研究了铌钒微化对中锰钢热加工性能的影响

中文摘要

中锰钢因其优异的力学性能和较低的合金成本被认为是第三代先进高强钢的理想候选材料之一。然而，目前对于中锰钢热变形行为的研究有限，尤其缺乏铌钒微合金化对中锰钢热变形行为影响的量化研究。本文通过单轴热压缩试验建立了本构方程，并进一步构建了变形激活能图和热加工图可识别导致金属流动失稳的工艺窗口，并对比总结了铌钒微合金化对中锰钢热变形的影响:（1）铌钒微合金化导致低速变形时动态再结晶所需的临界应变增加，但该增加量随着变形温度升高而逐渐减小至不明显，这表明低温下析出的碳化铌对中锰钢动态再结晶的抑制作用强于较高温下固溶Nb。（2）导致中锰钢的变形激活能显著提高，甚至高于一些高锰钢，表明铌钒微合金元素对动态再结晶的迟滞作用强于固溶锰。（3）铌钒微合金化缩小了热加工窗口中流动失稳区域，即更大程度地避免形成细小再结晶晶粒与粗大未再结晶晶粒的混晶组织，从而改善中锰钢的热加工性能。

Abstract

Abstract

The influence of Nb–V microalloying on the hot deformation behavior and microstructures of medium Mn steel (MMS) was investigated by uniaxial hot compression tests. By establishing the constitutive equations for simulating the measured flow curves, we successfully constructed deformation activation energy (Q) maps and processing maps for identifying the region of flow instability. We concluded the following consequences of Nb–V alloying for MMS. (i) The critical strain increases and the increment diminishes with the increasing deformation temperature, suggesting that NbC precipitates more efficiently retard dynamic recrystallization (DRX) in MMS compared with solute Nb. (ii) The deformation activation energy of MMS is significantly increased and even higher than that of some reported high Mn steels, suggesting that its ability to retard DRX is greater than that of the high Mn content. (iii) The hot workability of MMS is improved by narrowing the hot processing window for the unstable flow stress, in which fine recrystallized and coarse unrecrystallized grains are present.
