摘　　要：为分析C-Mn钢的动态再结晶行为,对单道次压缩过程进行了热模拟实验和数值模拟。研究表明,热模拟与数值模拟结果基本吻合;按照晶粒尺寸的不同,可将压缩试样分为4个区,试样分区的形状、大小与压缩变形量有关。In order to analyze the dynamic recrystallization of C-Mn steel, single compression test was carried out on thermal-mechanical simulator, meanwhile, the process was simulated by finite element software. It is shown that the experimental result is accordant with the numerical simulation, and the dynamic recrystallization model was verified. According to the austenitie grain sizes, section of the compression specimen can be divided into four zones, but shapes and sizes of each zone depend on the amount of compression.
