摘要：
The critical transformation temperatures,A;and A;,of a hot-rolled low-carbon titanium microalloyed steel were determined as a part of an examination of its phase-transformation behavior. Austenite decomposition during the continuous cooling of the titanium microalloyed steel was studied by heating it to 1 250 ℃,cooling it to880 ℃,holding for 2 s,and then cooling it to room temperature at different cooling rates. The transformation kinetics（ CCT curve） was characterized as well.
