摘要:

在变形温度为1000~1200 ℃、应变速率为0.01~50 s^-1、压下量为70%的条件下，使用Gleeble-3800热模拟实验机进行9310钢的等温热压缩，根据其微观组织和应力-应变曲线研究了这种钢的大应变(0.7~1.2)流动软化和应变硬化及其竞争机制。结果表明：在不同的变形参数范围内，9310钢的流动软化和应变硬化受到各种因素的影响。在高温(1080~1200 ℃)变形时其微观组织演变以动态再结晶(DRX)为主，影响流动软化和应变硬化的主要因素是应变速率。在高应变速率(5~50 s^-1)条件下影响其流动软化的主要因素是DRX；在应变速率(0.01~5 s^-1)较低时影响其应变硬化的主要因素是碳化物(CrC)钉扎。在低温(1000~1080 ℃)下变形，应变速率和变形温度对流动软化和应变硬化的影响都较为显著。随着应变速率的提高和变形温度的降低，变形热效应的影响逐渐增大，应变硬化程度随之降低。在低温和低应变速率条件下其应变硬化与DRX晶粒的粗化有关；在低温、高应变速率条件下存在大量原始形变奥氏体晶粒，组织演变是动态回复(DRV)，流动软化是变形热效应和DRV共同作用的结果。对变形后水冷组织的观察和EBSD分析结果表明，在水冷相变过程中DRX晶粒倾向于形成典型的马氏体多级结构，而原始形变奥氏体晶粒中较高的位错密度使这种结构受到破坏并使马氏体的形态混乱无序。

Abstract：

The isothermal thermal compression behavior of 9310 steel was assessed via Gleeble-3800 thermal simulation testing machine by applied pressing force up to 70% of the maximum value, with a range of strain rate 0.01-50 s^-1 at 1000-1200 ^oC, in terms of variation of the flow softening and strain hardening of 9310 steel by large strain (0.7-1.2). Then, the mechanism related with the competition of flow softening and strain hardening was clarified in combination with the microstructure evolution. The results show that the flow softening and strain hardening behavior of 9310 steels are affected by different factors in the range of different deformation parameters. When deformed within high temperature range (1080-1200 ^oC), the microstructure evolution is dominated by dynamic recrystallization (DRX), and the flow softening and strain hardening are mainly affected by the strain rate. The softening mechanism at high strain rate (5-50 s^-1) is DRX; The pinning effect of carbides is the main hardening mechanism at low strain rate (0.01-5 s^-1). When deformed within lower temperature range (1000-1080 ^oC), flow softening and strain hardening are significantly affected by strain rate and deformation temperature. With the increase of strain rate and the decrease of deformation temperature, the degree of strain hardening decreases gradually, and the influence of deformation thermal effect gradually increases. The hardening behavior by high strain rate at low temperature is related to the coarsening of DRX grains. There are a large number of original deformation austenite grains by high strain rate at low temperature, while the microstructure evolution is mainly dynamic recovery (DRV), and the flow softening is the result of the joint action of deformation heat effect and DRV. The observation of the deformed water-cooled structure and EBSD analysis showed that the DRX grains tended to form a typical martensite multi-level structure during the course water-cooling with phase transformation, however, which may be destroyed by the higher dislocation density in the original deformed austenite grains, thereby resulting in chaotic and disordered martensite morphology.
