摘　　要：采用单道次压缩实验方法 ,在Gleeble 1 5 0 0热模拟机上试验和测试了含硼微合金钢 (0 0 5C ,1 5 7Mn ,0 5Cu ,0 2 5Mo ,0 0 5Nb ,0 0 1Ti,0 0 0 1 2B)在不同变形速率下 1 0 0 0℃和 1 1 0 0℃时应力 应变曲线和热加工应变量对该钢晶粒尺寸的影响。Stress\|strain curves of boron bearing microalloy steel - 0 05C\|1 57Mn\|0 5Cu\|0 25Mo\|0 05Nb\|0 01Ti 0 0012B with different deformation rate at 1 000℃ and 1 100℃ and effect of strain of hot work on grain size of the steel were tested and measured by Gleeble 1500 hot simulator using single pass reduction test method. Based on the test data, a dynamic recrystallization dynamics model and a dynamic recrystallization grain size model for the boron bearing microalloy steel are established.
