摘　　要：研究了3种不同含Ti量(0.04％-0.16％Ti)钢奥氏体晶粒粗化温度及热轧后奥体再结晶的行为。在950-1200℃加热,含0.04％Ti钢奥氏体晶粒最小,其晶粒开始粗化温度在1150℃以上。得出含Ti钢开始再结晶的临界形变率(ε_c)与原始奥氏体晶粒直径(D_0)、轧制温度(T)间定量关系。The temperature of austenite grain coarsening and recrystallization parameters in steels containing 0.04%-0.16% Ti have been investigated.Experimental results show that after heating at 950-1 200℃ ,austenite grain size in 0.04% Ti-steel was the finest, and the temperature of grain coarsening was above 1 150℃ .The quantitative relationship between the critical reduction for austenite recrystallization εc and initinal austenite grain size Do at rolling temperature T has been obtained
