The continuous cooling transformation(CCT)curves of low carbon steel Q235(0. 15C

holding 10

15 and 25℃/s have been measured using dilatometry by Thermecmastor-Z thermal simulation machine. With prolonging holding time at intermediate roll table
the CCT phase transformation beginning and finishing curves moved down to right and grain size of steel at ambient gradually enlarged.
