Austenite Grain Coarsening and Recrystallization Parameters of Steel Containing Titanium

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 ε_c and initinal austenite grain size D_o at rolling temperature T has been obtained
